Description
Foreliggende oppfinnelse vedrører en spesiell fremgangsmåte til fremstilling av cefalosporinanaloge med den generelle formel: The present invention relates to a special method for the production of cephalosporin analogues with the general formula:
hvor X betyr amino, azido eller ftalylimido, og R kan være den samme som eller forskjellig fra R', som beskrives i det nedenstående, og betyr en karboksygruppe eller en karboksylatesterrest -COOR^, hvor R^har samme betydning som R^, som beskrives i det nedenstående, og denne fremgangsmåte er kjenne-tegnet ved at en forbindelse med den generelle formel: hvor Y betyr azido eller ftalylimido, RV betyr en karboksygruppe eller en karboksylatesterrest -COOR^, og R^betyr eventuelt halogenert alkyl med 1-5 karbonatomer, slik som metyl, etyl, n-propyl, isopropyl, n-'butyl, isobutyl, t-butyl, klormetyl, 2,2,2-trikloretyl éller 2,2,2-trifluor-etyl, arylmetyl med 7-20 karbonatomer, slik som benzyl, difenylmetyl eller trifenylmetyl, som eventuelt er substituert med metoksy, nitro eller lignende på fenylkjernen, eller substituert silyl slik som trimetyl eller trifenylsilyl, underkastes en ringslutningsreaksjon, og den resulterende cefalosporinanaloge med den generelle formel: where X means amino, azido or phthalylimido, and R can be the same as or different from R', as described below, and means a carboxy group or a carboxylate ester residue -COOR^, where R^ has the same meaning as R^, which is described below, and this method is characterized by a compound with the general formula: where Y means azido or phthalylimido, RV means a carboxy group or a carboxylate ester residue -COOR^, and R^ means optionally halogenated alkyl with 1-5 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl, chloromethyl, 2,2,2-trichloroethyl or 2,2,2-trifluoroethyl, arylmethyl with 7-20 carbon atoms, such as benzyl, diphenylmethyl or triphenylmethyl, which are optionally substituted with methoxy, nitro or the like on the phenyl nucleus, or substituted silyl such as trimethyl or triphenylsilyl, are subjected to a cyclization reaction, and the resulting cephalosporin analogue of the general formula:
hvor Y og R' har den ovenfor angitte betydning, reduseres. where Y and R' have the meaning indicated above, is reduced.
Man har tidligere syntetisert mange 3-H-karbacefem-derivater med den generelle formel: Many 3-H-carbacephem derivatives with the general formula have previously been synthesized:
hvor R^betyr hydrogen, lavere alkyl eller lavere acyloksy, where R^ means hydrogen, lower alkyl or lower acyloxy,
R2betyr hydrogen eller en esterrest, og X' betyr acyl, og har blant dem funnet noen forbindelser som utviser en meget sterk antibakteriell aktivitet overfor Gram-positive stammer og Gram-negative stammer, hvilke forbindelser er beskrevet i japansk publisert patentsøknad nr. 128.591/79, og britiske, patentsøknader nr. 2.017.102 og 2.107.103. R2 means hydrogen or an ester residue, and X' means acyl, and have found among them some compounds that exhibit a very strong antibacterial activity against Gram-positive strains and Gram-negative strains, which compounds are described in Japanese published patent application No. 128,591/79 , and UK Patent Applications Nos. 2,017,102 and 2,107,103.
Fundamentale trinn i fremstillingen av de angitte forbindelser med generell formel A (i det følgende for enkelt-hets skyld ofte betegnet som forbindelser A, og tilsvarende for andre forbindelser) er belyst ved følgende referanse-reaksjonsskjema I. Fundamental steps in the preparation of the indicated compounds of general formula A (in the following, for the sake of simplicity, often referred to as compounds A, and correspondingly for other compounds) are illustrated by the following reference reaction scheme I.
Referanse-reaksjonsskjerna I: Reference reaction nucleus I:
Det er også angitt at av forbindelsene A utviser de cis-isomere, hvori hydrogenatomene i 6- og 7-stillingene er i cis-stilling_til hverandre, meget større antibakteriell aktivitet enn de isomere hvori de to hydrogenatomene er i trans-konfigurasjon. Av utgangsmaterialene for forbindelsene A (R^=H) er de cis-isomere av forbindelsene med den generelle formel: It is also indicated that of the compounds A, the cis isomers in which the hydrogen atoms in the 6 and 7 positions are in the cis position to each other exhibit much greater antibacterial activity than the isomers in which the two hydrogen atoms are in the trans configuration. Of the starting materials for the compounds A (R^=H) are the cis-isomers of the compounds with the general formula:
hvor hydrogenatomene i 6- og 7-stilling er i cis-konfigurasjon i forhold til hverandre, viktige utgangsforbindelser for syntesen av forbindelsene A. where the hydrogen atoms in the 6- and 7-position are in cis configuration in relation to each other, important starting compounds for the synthesis of the compounds A.
Forbindelsene I' tilsvarende formel I, hvor X er amino eller azido, hvilke for første gang er angitt i forbindelse med foreliggende oppfinnelse, fremstilles ifølge den fremgangsmåte som er vist i det ovenfor angitte referanse-reaksjonsskjerna I. En lignende fremgangsmåte kan anvendes til fremstilling av forbindelsene I" tilsvarende formel I, hvori X er ftalylimido. The compounds I' corresponding to formula I, where X is amino or azido, which are indicated for the first time in connection with the present invention, are prepared according to the method shown in the above-mentioned reference reaction core I. A similar method can be used for the preparation of the compounds I" corresponding to formula I, in which X is phthalylimido.
Ved denne fremgangsmåte dannes alltid trans-isomere som biprodukter (for såvidt angår 3-laktamringen, transisomere hvori hydrogenatomene i 3- og 4-stilling er i trans-konfigurasjon i forhold til hverandre, og hva angår karbacefemringen, transisomere hvor hydrogenatomene i 6- og 7-stilling er i trans-konfigurasjon i forhold til hverandre), og derfor er kompliserte metoder som silisiumdioksydgel-kromatografi nød-vendige for isolering av ønskede cis-isomere, og cis-derivatene oppnås kun i lavt utbytte. Således er det ønske om en fremgangsmåte for syntetisering av cis-isomere av forbindelsene I' på en effektiv måte og i høyere utbytte. In this method, trans isomers are always formed as by-products (as far as the 3-lactam ring is concerned, trans isomers in which the hydrogen atoms in the 3- and 4-position are in trans-configuration in relation to each other, and as far as the carbacefem ring is concerned, trans isomers in which the hydrogen atoms in the 6- and 7-position are in trans-configuration relative to each other), and therefore complicated methods such as silica gel chromatography are necessary for the isolation of desired cis-isomers, and the cis-derivatives are only obtained in low yield. Thus, there is a desire for a method for synthesizing cis-isomers of the compounds I' in an efficient manner and in higher yield.
På den annen side har mari allerede angitt forbindelser II tilsvarende formel II, hvor Y er azido, og frem-gangsmåten til fremstilling av disse belyses i nedenstående referanse-reaksjonsskjerna II (britisk patentsøknad nr. 0006589) .. On the other hand, mari has already indicated compounds II corresponding to formula II, where Y is azido, and the method for preparing these is explained in the reference reaction core II below (British patent application no. 0006589) ..
Dessuten kan forbindelsene II omdannes til nyttige forbindelser med den generelle formel: Moreover, the compounds II can be converted into useful compounds with the general formula:
hvor X<1>og har den ovenfor angitte betydning, ved acyler-ing etter reduksjon av gruppen Y. Dette er også angitt i nevnte britiske patentsøknad nr. 0006589. where X<1>and has the above meaning, by acylation after reduction of the group Y. This is also stated in the aforementioned British patent application no. 0006589.
Referanse-reaksjonsskjema II: Reference Reaction Scheme II:
I det ovenstående reaksjonsskjerna har R' den tidligere angitte betydning, og R" betyr alkyl med 1-5 karbonatomer slik.som metyl,_.etyl, n-propyl, isopropyl, n-butyl eller isobutyl. In the above reaction core, R' has the previously stated meaning, and R" means alkyl with 1-5 carbon atoms such as methyl, ethyl, n-propyl, isopropyl, n-butyl or isobutyl.
Det er nå ifølge oppfinnelsen funnet en fremgangsmåte til fremstilling av forbindelsene II direkte ut fra forbindelsene III ved en ett-trinnsreaksjon og fremstilling av cis-derivatene av forbindelsene I på en enkel måte og i høyt utbytte ved reduksjon av forbindelsene II. According to the invention, a method has now been found for the preparation of the compounds II directly from the compounds III in a one-step reaction and the preparation of the cis-derivatives of the compounds I in a simple way and in high yield by reduction of the compounds II.
Oppfinnelsens formål er således å angi en forbedret fremgangsmåte til fremstilling av forbindelsene I, viktige utgangsforbindelser for syntesen.av forbindelsene A, og samtidig angi en hittil ukjent fremgangsmåte til fremstilling av de viktige forbindelser II. Videre fremgår det av nedenstående eksempler at foreliggende fremgangsmåte gjør det mulig å oppnå forbindelsene II i en isoleringsprosedyre ut fra azidoeddiksyre eller ftalylglycin. Således medfører foreliggende fremgangsmåte meget store industrielle fordeler. The purpose of the invention is thus to provide an improved method for the preparation of the compounds I, important starting compounds for the synthesis of the compounds A, and at the same time to provide a previously unknown method for the preparation of the important compounds II. Furthermore, it appears from the examples below that the present method makes it possible to obtain the compounds II in an isolation procedure from azidoacetic acid or phthalylglycine. Thus, the present method entails very large industrial advantages.
Oppfinnelsen skal beskrives mer detaljert i det følgende. The invention shall be described in more detail in the following.
Ifølge oppfinnelsen kan forbindelser med den generelle formel: hvor Y og R' har den ovenfor angitte betydning, fremstilles ved å underkaste forbindelser med den generelle formel: hvor Y, R<1>ogR" har den ovenfor angitte betydning, en ringslutningsreaksjon. Denne reaksjon gjennomføres fortr-inasvis i et oppløsningsmiddel i nærvær av en base. Som base til anvendelse i reaksjonen kan f.eks. nevnes tertiære aminer, slik som trietylamin, N-metylmorfolin, dimetyletanolamin, 4-dimetylaminopyridin og 1,4-diazabicyklo[2,2,2]oktan (PAJ3C0) , sekundære aminer med stor sterisk hindring, slik som dicyklo-heksylamih, dietylamin og diisopropylamin, metallalkoholater med begrenset nukléofilitet slik som kalium-t-butoksyd, og videre natriumacetat, natriumhydrogenkarbonat, natriumkar-bonat og natriumhydrid. Dimetyletanolamin,. DABCO, N-metyl-morf olin, trietylamin og 4-dimetylaminopyridin er spesielt fordelaktige. Dessuten kan noen av basene også benyttes som oppløsningsmiddel. According to the invention, compounds of the general formula: where Y and R' have the above meaning can be prepared by subjecting compounds of the general formula: where Y, R<1> and R" have the above meaning to a ring closure reaction. This reaction is preferably carried out in a solvent in the presence of a base. As a base for use in the reaction, mention may be made, for example, of tertiary amines, such as triethylamine, N-methylmorpholine, dimethylethanolamine, 4-dimethylaminopyridine and 1,4-diazabicyclo[2, 2,2]octane (PAJ3C0), secondary amines with great steric hindrance, such as dicyclohexylamih, diethylamine and diisopropylamine, metal alcoholates with limited nucleophilicity such as potassium t-butoxide, and further sodium acetate, sodium bicarbonate, sodium carbonate and sodium hydride. Dimethylethanolamine, DABCO, N-methylmorpholine, triethylamine and 4-dimethylaminopyridine are particularly advantageous, and some of the bases can also be used as solvents.
Reaksjonen kan gjennomføres i fravær av et oppløs-ningsmiddel, men den gjennomføres fortrinnsvis i et inert oppløsningsmiddel som ikke påvirker reaksjonen, f.eks. et aromatisk hydrokarbon slik som benzen, toluen eller xylen, The reaction can be carried out in the absence of a solvent, but it is preferably carried out in an inert solvent which does not affect the reaction, e.g. an aromatic hydrocarbon such as benzene, toluene or xylene,
en ester slik som etylacetat eller metylacetat, en eter slik som étyleter, tetrahydrofuran eller dimetoksyetan, et halogenert hydrokarbon slik som metylenklorid, kloroform eller karbontetraklorid, et amin slik som dimetylformamid eller dimetylacetamid, en alkohol slik som metanol, etanol, isopropanol, t-butanol eller etylenglykol-monometyleter, et sulfoksyd slik som dimetylsulfoksyd, pyridin eller acetonitril. Disse oppløsningsmidler kan anvendes alene i kombinasjoner an ester such as ethyl acetate or methyl acetate, an ether such as ethyl ether, tetrahydrofuran or dimethoxyethane, a halogenated hydrocarbon such as methylene chloride, chloroform or carbon tetrachloride, an amine such as dimethylformamide or dimethylacetamide, an alcohol such as methanol, ethanol, isopropanol, t-butanol or ethylene glycol monomethyl ether, a sulfoxide such as dimethyl sulfoxide, pyridine or acetonitrile. These solvents can be used alone in combinations
av to eller flere. Spesielt ønskede oppløsningsmidler in-kluderer aromatiske hydrokarboner, etere, estere og alkoholer. of two or more. Particularly desired solvents include aromatic hydrocarbons, ethers, esters and alcohols.
Reaksjonen gjennomføres vanligvis ved temperaturerThe reaction is usually carried out at temperatures
fra romtemperatur til 100°C, men den kan også foregå under avkjøling med. is, selv om reaksjonshastigheten er lav. Reaksjonen gjennomføres mest ønsket ved romtemperatur for å undertrykke sidereaksjoner. from room temperature to 100°C, but it can also take place during cooling with ice, although the reaction rate is low. The reaction is most preferably carried out at room temperature to suppress side reactions.
Reaksjonen gjennomføres vanligvis i fra 30 minutter til 10 timer. Reaksjonen fullføres på 3-6 timer ved romtemperatur eller på 1-3 timer under oppvarming. The reaction is usually carried out for from 30 minutes to 10 hours. The reaction is completed in 3-6 hours at room temperature or in 1-3 hours under heating.
Reaksjonsproduktet isoleres og renses på konvensjonell måte. Produktet fra foreliggende fremgangsmåte kan meget lett utskilles og renses på grunn av den s.otre forskjell i polaritet fra utgangsforbindelsen og biproduktene. Oppfinnelsen gjør det mulig på en meget lett måte å fremstille forbindelsene II i et trinn utfra forbindelsene III. Det er absolutt uventet at forbindelsene II, som har en ring-spenning, kan fremstilles, utfra et forholdsvis mindre reak-tivt a,p-umettet aldehyd ved den såkalte Horner-Wittig-reaksjon, og spesielt at det utfra forbindelsene III kan fremstilles forbindelser II som utfra NMR-spektret øyen-synlig har trans-form i dobbeltbindingen. The reaction product is isolated and purified in a conventional manner. The product from the present process can be very easily separated and purified due to the apparent difference in polarity from the starting compound and the by-products. The invention makes it possible in a very easy way to prepare the compounds II in one step from the compounds III. It is certainly unexpected that compounds II, which have a ring tension, can be prepared from a relatively less reactive a,p-unsaturated aldehyde by the so-called Horner-Wittig reaction, and especially that compounds can be prepared from compounds III II which, based on the NMR spectrum, clearly has a trans form in the double bond.
Utgangsforbindelsene III som benyttet i dette trinn, syntetiseres ved den fremgangsmåte som er angitt i britisk patentskrift nr. 2.017.102 eller ved en analog fremgangsmåte. The starting compounds III used in this step are synthesized by the method indicated in British patent document No. 2,017,102 or by an analogous method.
Reduksjon av forbindelsene II, fremstilt som beskrevet ovenfor gir forbindelsene I. I dette reduksjonstrinn reduseres dobbeltbindingen i 4,5-stilling selektivt, og om nød-vendig, kan azidogruppen samtidig reduseres til en aminogruppe ved passende valg av reaksjonsbetingelser. Reduction of compounds II, prepared as described above, yields compounds I. In this reduction step, the double bond in the 4,5-position is selectively reduced, and if necessary, the azido group can be simultaneously reduced to an amino group by suitable choice of reaction conditions.
Som reduksjonsmetode benyttes hovedsakelig katalytisk reduksjon med hydrogen under atmosfæretrykk eller.under for-høyet trykk. Som katalysator kan f.eks. anvendes palladium på bærer, platina på bærer, rhodium på bærer, ruthenium på bærer, platinaoksyd, Raney-nikkel, rutheniumoksyd osv. Dessuten kan reduksjon av azidogruppen gjennomføres ved endring av katalysatormengden, dvs. azidogruppen kan etterlates uredusert,hvis katalysator anvendes i en liten mengde, eller kan reduseres til en aminpgruppe ved anvendelse av katalysatoren i en stor mengde. Catalytic reduction with hydrogen under atmospheric pressure or under elevated pressure is mainly used as a reduction method. As a catalyst, e.g. palladium on a support, platinum on a support, rhodium on a support, ruthenium on a support, platinum oxide, Raney nickel, ruthenium oxide, etc. are used. Furthermore, reduction of the azido group can be carried out by changing the amount of catalyst, i.e. the azido group can be left unreduced, if the catalyst is used in a small amount, or can be reduced to an amine group by using the catalyst in a large amount.
Som oppløsningsmiddel anvendes f.eks. vann, alkoholer slik som etanol og metanol, etere slik som dioksan og tetrahydrofuran, estere slik som etylacetat, hydrokarboner slik som cykloheksan, eddiksyre eller trifluoreddiksyre alene eller i kombinasjon. Oppløsningsmidler med en forholdsvis lav polaritet slik som etylacetat eller oppløsningsmidler av eterrekken, er ønskelige hvis azidogruppen skal etterlates, og oppløs-ningsmidler av alkoholrekken slik som etanol foretrekkes til samtidig reduksjon av azidogruppen. til en aminogruppe. As a solvent, e.g. water, alcohols such as ethanol and methanol, ethers such as dioxane and tetrahydrofuran, esters such as ethyl acetate, hydrocarbons such as cyclohexane, acetic acid or trifluoroacetic acid alone or in combination. Solvents with a relatively low polarity such as ethyl acetate or solvents of the ether series are desirable if the azido group is to be left, and solvents of the alcohol series such as ethanol are preferred for simultaneous reduction of the azido group. to an amino group.
Hvis man ønsker å.redusere azidogruppen til en.aminogruppe, tjener samtidig tilstedeværelse av en mineralsyre slik som saltsyre, eller en organisk syre slik som eddiksyre If one wishes to reduce the azido group to an amino group, the simultaneous presence of a mineral acid such as hydrochloric acid, or an organic acid such as acetic acid serves
eller trifluoreddiksyre, til å fremskynde reaksjonen.or trifluoroacetic acid, to accelerate the reaction.
Når har betydningen benzyl, p-nitrobenzyl, difenylmetyl, trityl eller lignende, medfører denne katalytiske reduksjon i noen tilfeller fjerning av estergruppen under dannelse av R3til et hydrogenatom. Videre når R3 betyr tertiær butyl, trityl eller lignende, omdannes R^ i noen tilfeller til et hydrogenatom når reduksjonen gjennomføres i en sterk syre slik som trifluoreddiksyre. When the meaning is benzyl, p-nitrobenzyl, diphenylmethyl, trityl or the like, this catalytic reduction in some cases entails the removal of the ester group while forming R3 to a hydrogen atom. Furthermore, when R 3 means tertiary butyl, trityl or the like, R 3 is in some cases converted into a hydrogen atom when the reduction is carried out in a strong acid such as trifluoroacetic acid.
Reduksjonen gjennomføres vanligvis ved temperaturerThe reduction is usually carried out at temperatures
fra romtemperatur til 100°C, fortrinnsvis ved romtemperatur. Imidlertid kan den gjennomføres ved temperaturer utenfor det nevnte område. Reaksjonstiden varierer avhengig av katalysator-ens art og mengde, oppløsningsmidlets art og tilstedeværelsen eller fraværet av syre, men reaksjonen fullføres vanligvis på fra 30 minutter til 10 timer. Isolering og rensing av reaksjonsproduktet kan gjennomføres på konvensjonell måte for katalytiske reduksjoner. from room temperature to 100°C, preferably at room temperature. However, it can be carried out at temperatures outside the mentioned range. The reaction time varies depending on the nature and amount of the catalyst, the nature of the solvent, and the presence or absence of acid, but the reaction is usually completed in from 30 minutes to 10 hours. Isolation and purification of the reaction product can be carried out in a conventional manner for catalytic reductions.
