Dansk: Patent Kontor ApS.__ i5*) Fungicide anilidforbindelser til anvendelse ved plantebeskyttelse.
Den foreliggende opfindelse angår fungicide anilidforbindeløer '*.
til anvendelse ved plantebeskyttelse, og disse forbindélser ' ejendommelige ved, at de bar formlen : ’CH, ' v' ' ' - ·^ :: | 3 ? ?H3 CH-C00CH, ; 1 ; i., ·:' W \-0 CH3 , NT , hvori R er hydrogen eller methyl. . :vil - / 2 141168
Bakterie- og svampesygdomme bos nytteplanter begunstiges af to fakto rer. Por det første tilstræbes ved planteavlsarbejde i første række udbytteforøgelse og kvalitetsforbedring. Hyppigt går derved dog en del af plantens naturlige modstandskraft overfor parasitter tabt. Por det andet bar erfaringen vist, at bakterier og skadelige svampe i årenes løb bar udviklet resistens mod de kendte pesticider i større målestok.
Der består derfor et påtrængende bebov for mikrobicider, der tåles af kulturplanter, og som tilintetgør deres direkte parasitter.
Kulturplanter er f.eks. kom, majs, ris, grøntsager, sukkerroer, soja, jordnødder, frugttræer, prydplanter, men fremfor alt vinplanter, humle, agurkevækster (agurker, græskar, meloner), solanaceer, såsom kartofler, tobak og tomater, samt også banan-, kakao- og naturkautsjuk-vasks t er.
Pra tysk fremlæggelsesskrift nr. 1.768.686 og tysk offentliggørelsesskrift nr. 2.006.471 kendes anilider, der har lignende struktur som forbindelserne med formlen I. Ved de nedenfor angivne "Porsøg 1" og "Porsøg 2" viste sådanne kendte forbindelser ingen eller belt utilstrækkelig virkning som fungicider til plantebeskyttelse. Ved forsøgene fandt man derimod overraskende, at forbindelserne med formlen I viser en stærk fungicid virkning.
Med forbindelserne med formlen I kan svampe, der optræder på planter eller plantedele (frugter, blomster, løvværk, stængler, knolde, rødder) af disse og andre nytrekulturer, altså hæmmes eller tilin-tetgøres, hvorved også senere tilvoksende plantedele forbliver forskånet for sådanne svampe. Porbindelserne er virksomme mod fy-topatogene svampe, der tilhører følgende klasser: Ascomycetes (f.eks. Erysiphaceae); Basidiomycetes, såsom fremfor alt rustsvampe; Pungi imperfect!; men især mod de til klassen Phycomycetes hørende Oomycetes, såsom Phytophthora, Peronospora, Pseudoperono-spora, Pythium eller Plasmopara. Desuden virker forbindelserne med formlen I systemisk.
De kan endvidere anvendes som bejdsemidler til behandling af såmate-riale (frugter, knolde, kom) og plant es tiklinger til beskyttelse mod svampeinfektioner samt mod fytopatogene svampe, der optræder i jorden.
3 141168 N-(Subst. phenyl )-K-furanoyl-alanin-methyl es terne med formlen I udgør en hidtil ukendt klasse af hidtil ukendte mikrobicidt virksomme stoffer, der på deres anvendelsesområde er de sædvanlige handelspræparater tydeligt overlegne.
Forbindelserne med formlen I fremstilles f. eks. ved acylering af en forbindelse med formlen R CH, rrf
Il 3 f3 X-RH-CH-COOCH3 (II) CH3 med furan-(2) -carboxyl syre, dens syrehal o genid, syreanhydrid eller estere, i enkelttilfælde også med et furan-(2)-carboxylsyreamid (om-amidering).
Ifølge en anden metode kan forbindelserne med formlen I også fremstilles ved, at et acylanilid med formlen R CH3 <zSt°‘U (in)
I H
ch3 med butyl-lithium eller Ha-hydrid overføres til det tilsvarende alkalimetalsalt, hvorpå dette med en α-halogenpropionsyremethylester overføres til det ønskede slutprodukt, eller man kan omsætte acylanilidet med a-halogenpropionsyremethylesteren i nærværelse af et alkalimetal -carbonat, såsom K^CO^ som protonacceptor, fortrinsvis under tilsætning af katalytiske mængder alkalimetaliodid, f.eks. KJ.
I formlerne II og III er R hydrogen eller methyl, udtrykket syrehalo-genid betyder fortrinsvis syrechlorid eller syrebromid, og halogenatomet i α-halogenpropionsyremethylesteren er fortrinsvis chlor eller brom. Omsætningerne kan gennemføres i nær- eller fraværelse af opløsnings- eller fortyndingsmidler, der er inaktive overfor reaktionsdel-tageme. På tale kommer f. eks. følgende: aliphatiske eller aromatiske carbonhydrider, såsom benzen, toluen, xylener, petroleumsether; halo- 4 141168 generede carbonhydrider, såsom chlorbenzen, methylenchlorid, ethylen-chlorid, chloroform; ethere og etheragtige forbindelser, såsom di al kyl ethere, dioxan, tetrahydrofuran; nitriler, såsom acetonitril; Η,Η-dialkylerede amider, såsom dimethylformamid; vandfri eddikesyre, di-methylsulfoxid, ketoner, såsom methylethylketon, og blandinger af sådanne opløsningsmidler indbyrdes.
Reaktionstemperatureme ligger mellem 0 og l80°C, fortrinsvis mellem 20 og 120°C. I mange tilfælde er anvendelsen af syrebindende midler eller kondensationsmidler fordelagtig. Som sådanne kommer i betragtning tertiære aminer, såsom trialkylaminer (f.eks. triethylamin), pyridin og pyridinbaser, eller uorganiske baser, såsom oxider og hydroxider, hydrogenearbonater og carbonater af alkali- og jordalkalimetaller samt natriumac etat. Som syrebindende middel kan desuden anvendes et overskud af det pågældende anilinderivat med formlen II.
Den fremstillingsmetode, der går ud fra forbindelser med formlen II, kan også gennemføres uden syrebindende midler, hvorved det i nogle tilfælde kan være på sin plads med gennemledning af nitrogen til fordrivelse af det dannede hydrogenhalogenid. I andre tilfælde er en tilsætning af dimethyl f o imamid som reaktionskatalysator meget fordelagtig.
Enkeltheder angående fremstillingen af mellemprodukterne med formlen II kan udledes af de metoder, der alment er angivet om fremstillingen af anilino-alkansyreestere i følgende publikationsorganer: J.Org. Chem.
30, 4101 (1965), Tetrahedron 1967, 487, og Tetrahedron 1967, 493·
Forbindelserne med formlen I har i propionsyreesterkæden et asymmetrisk carbonatom og kan på sædvanlig måde spaltes i optiske antipoder. Herved har den enantiomere D-form den stærkeste mikrobicide virkning.
Man foretrækker derfor forbindelser med formlen I, der har D-konfigu-ration. Disse D-former har i ethanol eller acetone en negativ drejningsvinkel.
Til fremstilling af de rene optiske D-antipoder fremstilles f.eks. den racemiske forbindelse med formlen : 5 141168 H CH, ηπ II 3 f3 X-NH-CH-COOH (IV) CH3 (R * H eller CH3) og denne omsættes så på i og for sig kendt måde med en N-holdig optisk aktiv base til det tilsvarende salt. Ved fraktioneret krystallisation af saltet og efterfølgende frigørelse af den med den optiske B-enti-pode berigede syre med formlen IV og eventuelt gentagelse (også flere ganges gentagelse) af saltdannelsen, krystallisationen og frigørelse . af a-anilinopropionsyren med formlen IV vinder man trinvis den rene D-form. Af denne kan så på sædvanlig måde, f.éks. i nærværrise af HC1 eller EDjSO^, med methanol vindes den optiske D-konfiguration af esteren med formlen II. Som optisk aktiv organisk base kommer f.eks. a-phenyl ethyl amin på tale.
I stedet for ved fraktioneret krystallisation kan den enantiornere D-form med formlen IV også vindes ved udbytning af hydroxylgruppen i den naturligt forekommende 1(+)-mælkesyre med halogen og videreresktion af dette produkt under konfigurationsomvendrise med den ønskede 2,6-di-methylanilin eller 2,3,6-trimethylanilin.
Foruden den optiske isomeri optræder i tilfældet R » CH^ med furanoy-leringen af forbindelsen II (eller med reaktion af forbindelse III med a-halogenpropionsyremethylester) en atropisomeri om ph.enyl-N< aksen, betinget af den steriske hindring af de to ved N-atomet i trimethyl-anilinen ekstra indførte grupper.Såfremt der ikke gennemføres nogen målrettet syntese til isolering af rene isomere, fås den nedennævnte forbindelse nr. 2 ved fremstillingen som en blanding af 4 isomere.
Den gunstigere fungicide virkning af den enantiomere D-form (i sammenligning med D,L-formen eller L-formen) forbliver dog bevaret og påvirkes ikke nævneværdigt af atropisomerien.
Fremstillingen af de virksomme stoffer med formlen I belyses af eksemplerne 1 og 2.

Efter at den svagt eksoterme reaktion er klinget af, opvarmes i 5 timer under tilbagesvaling, og det dannede hydrogenchlorid fjernes fuldstændigt ved gennemledning af nitrogen. Efter fjernelse af opløsningsmidlet destilleres i vakuum; kp. 166-l68°C/0,06 mm Hg. Det størknede slutprodukt smelter efter om-krystallisation af toluen/petroleumsether ved 81-84·°C. Eøntgenpulverdiagrammer viser, at forbindelsen er polymorf. En af de to modifikationer smelter ved 85°C.

b) Til en suspension af 33,5 g (0,152 mol) af den ifølge a) opnåede ester og 18 g (0,17 mol) natriumcarbonat i 200 ml absolut benzen sættes dråbevis 16,7 ml (0,17 mol) furan-2-carboxylsyrechlorid ved 60-70°C, og denne temperatur holdes i 4 timer. Efter afkøling, filtrering og inddampning af filtratet krystalliserer slutproduktet af isopropyl-ether; smp. 98-102°C.
Når man acylerer D-formen af a-(2,3,6-trimethylanilino)-propionsyre-methylester med furan-(2)-carboxylsyre eller et af dens reaktionsdygtige derivater, får man D-formen af forbindelsen 2 som en blanding af atropisomere (forbindelse nr. 2a). Den opnåede procentuelle mængde af hver af disse isomere er afhængig af de pågældende fremstillingsbetingelser.
