Description
Fremgangsmåte for fremstilling av terapeutisk virksomme furanderivater.
Foreliggende oppfinnelse angår en
fremgangsmåte for fremstilling av nye furanderivater med den alminnelige formel I:
hvor X er en rett eller forgrenet alkylen-kjede med 2—10 karbonatomer som kan
være substituert med 1-—2 monocykliske
arylgrupper, og det særegne ved fremgangsmåten består i at 5-nitro-2-furaldehyd kondenseres med en toverdig alkohol med den
alminnelige formel II:
hvor X har samme betydning som ovenfor.
Fremgangsmåten kan eksempelvis ut-føres på følgende måte: En oppløsning av
5-nitro-2-furaldehyd og en toverdig alkohol med formel II, f. eks. etylenglykol,i et
indifferent organisk oppløsningsmiddel, f.
eks. benzen, toluen eller xylen blir oppvarmet til koking under tilbakeløp fortrinns-vis under bruk av en vannavskiller, hvorunder hovedmengden av det vann som dan-nes ved kondenseringen skilles ut allerede
i de rørste timer. For å fullføre reaksjonen
pier det foretatt oppvarming til koking med
tilbaktløp i ennå flere timer. Det ønskete
sluttprodukt blir isolert på kjent måte fra
reaksjonsblandingen og renset ved destil-lering og/eller omkrystallisering.
De hittil ukjente furanderivater som fremstilles etter foreliggende fremgangsmåte har verdifulle terapeutiske egenska-per. Således bevirker de etter peroral bruk en utvidelse av de perifere blodkar og der-med en senking av blodtrykket. Herunder har det vist seg, og dette er av spesiell betydning for terapien, at denne blodtrykk-senking inntrer uten vesentlig påvirkning av hjerteslagfrekvensen. Elektrokardiogra-fiske undersøkelser viser at disse forbindelser i doser som virker blodtrykksenkende ikke påvirker bevegelsesforløpet i hjertet. Den terapeutiske anvendelse av disse forbindelser er ikke ledsaget av ikke ønske-lige kardiale sidefenomener. Forbindelser som er fremstillet i henhold til oppfinnelsen har også meget liten alminnelig giftighet. Det er dessuten av spesiell betydning at den terapeutiske virkning holder seg. Således holder blodtrykksenkningen seg i flere timer etter en gangs bruk av de nye forbindelser. De forbindelser som er fremstillet etter fremgangsmåten skal derfor brukes terapeutisk ved kretsløpforstyrrelser; spe-sielt ved høytrykk og ved forstyrrelser i blodsirkulasjonen inkl. angina pectoris.
I de følgende eksempler som skal il-lustrere fremgangsmåten er alle tempera-turangivelser i celsiusgrader. Smelte- og koke-punktene er ikke korrigert.
Eksempel 1:
2-( 5'- nitrofuryl- 2') - 1, 3- dioksolan.
En blanding av 28,2 g 5-nitro-2-fural-dehyd, 13,6 g etylenklykol og noen krystaller p-toluensulfonsyre i 150 cm<8> benzen ble oppvarmet til koking i 16 timer i en kolbe som var forsynt med vannutskiller og til-bakeløpskjøler. Hovedmengden av det dan-nete vann skilte seg ut allerede i de to første timer. Derpå ble det dekantert av fra harpiksaktige rester, benzenen ble dampet av i vakuum og resten revet med petroleter, hvorunder det inntrådte krystalliser-ing. Etter to gangers omkrystallisering fra etanol eller eter/petroleter smeltet 2-(5'-nitrofuryl-2')-l,3-dioksolan ved 44—45°.
Eksempel 2: 2- ( 5'- nitrofuryl- 2') - 4( 5)- metyl-1, 3- dioksolan
En blanding av 28,2 g 5-nitro-2-fural-dehyd, 16,7 g 1,2-propandiol og noen krystaller p-toluensulfonsyre i 150 cm<3> benzen ble oppvarmet i 16 timer slik som beskrevet i eksempel 1. Etter avdekantering fra har-piksllknende rester ble benzenen dampet av i vakuum og resten destillert i vakuum, hvorunder 2-(5'-nitrofuryl-2')-4(5)-metyl-1,3-dioksolan gikk over ved 141° ved 1,1 mm Hg som en svak gulfarget olje.
Eksempel 3: 2-( 5'- nitrofuryl- 2') - 4( 6) - metyl- l, 3- dioksan
En blanding av 28,2 g 5-nitro-2-fural-dehyd, 19,8 g 1,3-butandiol og noen krys-teller p-toluensulfonsyre i 150 cm<3> benzen ble oppvarmet i 15 timer slik som beskrevet i eksempel 1. Etter avdekantering fra har-piksliknende rester og fjerning av benzenen i vakuum ble den krystalline, gule rest om-krystallisert fra eddiksyreetylester/petroleter. Smp. 106—107°.
Eksempel 4: 2-( 5''- nitrofuryl- 2'')- 1, 3- dioksepan.
En blanding 28,2 g 5-nitro-2-furalde-hyd, 19,8 g 1,4-butandiol og noen krystaller p-toluensulfonsyre i 150 cm<3> benzen ble oppvarmet i 2 timer slik som beskrevet i eksempel 1. Etter avdekantering fra harpiksaktige rester og fjerning av benzenen i vakuum ble den krystalline rest revet med en blanding av metanol/eter og filtrert av. Smp. 87—89° etter to gangers omkrystallisering fra benzen/petroleter.
Eksempel 5:
2-( 5,- nitrofuryl- 2')- l, 3- dioksonan.
En blanding av 28,2 g 5-nitro-2-fural-dehyd, 25,9 g 1,6-heksandiol og noen krys-
tallre p-toluensulfonsyre i 150 cm<3> benzen ble oppvarmet i 16 timer slik som beskrevet i eksempel 1. Etter avdekantering fra har-piksliknende rester ble benzenen dampet av i vakuum og resten kokt opp med 200 cm<3> aceton. Det ble foretatt avkjøling, den utskilte krystallmasse ble filtrert av og filterresten krystallisert fra pyridin. Smp. 189—191°.
Eksempel 6:
2- ( 5''- nitrofuryl- 2'') - 4, 5- difenyl 1, 3- dioksolan.
En blanding av 14,1 g 5-nitro-2-fural-dehyd, 23,4 g hydrobenzoin (blanding av meso- og rac.-form) og noen krystaller p-toluensulfonsyre i 100 cm<3> benzen ble oppvarmet i 5 timer slik som beskrevet i eksempel 1. Etter avdekantering fra har-piksliknende rester og f j erning av benzenen i vakuum ble den krystalline rest omkrys-tallisert fra benzen. 2-(5'-nitrofuryl-2')-4,5-difenyl-l,3-dioksolan smeltet ved 168°.
Fra den benzeniske moderlut kan det ved inndamping og tilsetting av litt petroleter fremstilles den stereoisomere forbind-else med smp. 133—135°.
Eksempel 7: 2- ( 5'- nitrofuryl- 2') - 4( 6)- fenyl-5, 5- dietyl- l, 3- dioksan.
En blanding av 14,1 g 5-nitro-2-fural-dehyd, 22,8 g l-fenyl-2,2-dietyl-l,3-propandiol og noen krystaller p-toluensulfonsyre i 150 cm<3> benzen ble oppvarmet i 6 timer slik som beskrevet i eksempel 1. Hovedmengden av det vann som ble dannet skilte seg ut allerede i de første to timer. Derpå ble det foretatt dekantering fra harpiks-liknende rester, benzenen ble dampet av i vakuum og den mørkebrune, oljeliknende rest ble kromatografert på aluminiumok-syd, hvorunder 2-(5'-nitrofuryl-2')-4(6)-fenyl-5,5-dietyl-l,3-dioksan ble eluert med benzen. Etter omkrystallisering fra benzen/ petroleter smeltet dioksanderivatet ved 85—86°.
På liknende måte som beskrevet i de foregående eksempler ble det fra 5-nitro-2-furaldehyd og en toverdig alkohol i nær-vær av noen krystaller p-toluensulfonsyre oppnådd føigende forbindelser:
