Den foreliggende opfindelse angår hidtil ukendte, fungicide, eventuelt halogensubstituerede furan(2)- eller tetrahydrofuran(2)-carboanilider til anvendelse ved plantebeskyttelse eller andre tekniske formål. Forbindelserne ifølge opfindelsen er ejendommelige ved, at de har den almene formel R1 ,

C-,-C ^-alkyl eller halogen, er hydrogen, C-^-C^-alkyl eller halogen, R° er hydrogen eller methyl, idet det samlede antal C-atomer i sub- stituenterne R^, R^, R^ og R^ i phenylringen ikke overstiger tallet 8, X er -CH2- eller fH3, R^ er -COOR' eller -COR^R" , hvor R’, R" -GH- XR"' og R"1 uafhængigt af hinanden er hydrogen,methyl eller ethyl, og R^ er eventuelt med halogen substitueret 2-furanyl eller 2-tetrahydro-furanyl, med den bestemmelse, at phenylringen indeholder en yderligere substituent, når den er substitueret i 2,6- eller 2,3,6-stilling med methyl, og når samtidig R^ er en 2-furanylgruppe og -X-R^ en a-propionsyremethylestergruppe.
Ved alkyl og som aikyldel af en alkoxygruppe skal alt efter antallet af de angivne carbonatomer forstås følgende grupper: methyl, ethyl, n-propyl, isopropyl eller n-, iso-, sek.- eller tert.butyl. Som halogen kommer fluor, chlor, brom eller iod på tale.
Pra tysk offentliggørelsesskrift nr. 2.006.471 kendes (2'-methyl-furanyl-3')-carbonyl-2,6-dimethylanilin og (21-methylfuranyl-3')-carbonyl-2-methyl-6-ehloranilin som aktive stoffer med moderat virkning mod visse svampe (Uromyces phaseoli, Altemaria solani, Rhizoc-tonia solani).
Det har nu overraskende vist sig, at forbindelser med den tydeligt afvigende struktur med formlen I har et for de praktiske behov meget gunstigt fungicid-spektrum til beskyttelse af kulturplanter. Kulturplanter er her 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 naturkautsjukvækster.
Med de virksomme stoffer med formlen I kan optrædende svampe på planter eller plantedele (frugter, blomster, løvværk, stængler, knolde, rødder) af disse og andre nyttekulturer hæmmes eller dræbes, idet også senere tilvoksende plantedele forbliver forskånet for sådanne 3 141995 svampe. De aktive stoffer er virksomme mod fytopatogene svampe, der tilhører følgende klasser: Ascomycetes (f.eks. Erysiphaceae), Basidio-mycetes, såsom fremfor alt rustsvampe, Fungi imperfecti, men især mod de til klassen Fhycomycetes hørende Oomycetes, såsom Phytophthora, Peronospora, Pseudoperonospora, Pythium eller Plasmopara. Desuden virker forbindelserne med formlen I systemisk. De kan endvidere anvendes som bejdsemidler til behandling af såmateriale (frugter, knolde, kom) og plantestiklinger til beskyttelse mod svampeinfektioner samt mod fytopatogene svampe, der optræder i jorden.
Foretrukne som fungicider er forbindelser med formlen I, hvori R^ 2 er methyl, R står i ortho-stilling til aminogruppen og er methyl, ethyl eller chlor, -X-R3 er grupperingen 9^3 , medens R4, R^, 6 -CH-COOR' R og R1 har den angivne betydning. Disse skal benævnes forbindelsesgruppe la.
Blandt disse forbindelser la skal fremhæves dem, hvori R4 er en usubstitueret 2-furanylgruppe.
Fremstillingen af forbindelserne med formlen I sker f.eks. ved acyle-ring af en forbindelse med formlen R5 J >X-R3 (id r6/Z lp
R
med en carboxylsyre med formlen HO-CO-R4 (III) eller dens syrehalogenid, syreanhydrid eller ester, i enkelttilfælde også med et af dens syreamider (omamidering).
Ifølge en anden metode kan forbindelserne med formlen I fremstilles ved, at man overfører acylanilider med formlen 5 Kl
_I
V -NH-CO-R4 (IV) 4 141995 med butyl-lithium eller Ha-hydrid til det tilsvarende alkalimetalsalt, der så med en forbindelse med formlen
Hal-X-R3 (V) fører til det ønskede slutprodukt, eller ved, at man omsætter acyl-anilideme med formlen IV med forbindelsen med formlen V i nærværelse af et alkalimetalcarbonat (såsom NagCO^ eller K^CO^) som protonaccep-tor, fortrinsvis under tilsætning af katalytiske mængder alkalimetal -iodid (såsom KJ).
-i c I formlerne II, III, IV og V har R til R og X den under formlen I angivne betydning, medens Hal er et halogenatom, fortrinsvis chlor eller brom, eller en anden let fraspaltelig gruppe. Begrebet "syrehalo-genid" står fortrinsvis for syrechloridet eller syrebromidet.
Omsætningerne kan gennemføres i nær- eller fraværelse af opløsningseller fortyndingsmidler, der er inaktive overfor reaktionsdeltagerne. På tale kommer f.eks. følgende: aliphatiske eller aromatiske carbon-hydrider, såsom benzen, toluen, xylener, petroleums ether, halogenerede carbonhydrider, såsom chlorbenzen, methylenchlorid, ethylenchlorid, chloroform,, ethere og etheragtige forbindelser, såsom di alkyl e there, dioxsn, tetrahydrofuran, nitriler, såsom acetonitril, H,H-dialkylerede amider, såsom dimethylformarnid; vandfri eddikesyre, dimethylsulfoxid, ketoner, såsom methylethylketon, og blandinger af sådanne opløsningsmidler indbyrdes.
Reakt i ons temp er atur erne ligger mellem 0 og l80°C, fortrinsvis mellem 20 og 120°C. I mange tilfælde er anvendelse 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, hydrogencarbonater og carbonater af alkali- og jordalkalime-taller samt natriumacetat. Som syrebindende middel kan desuden ved den første fremgangsmåde anvendes et overskud af det pågældende anilinderivat med formlen II.
Fremgangsmåden, der går ud fra forbindelser med formlen II, kan også gennemføres uden syrebindende midler, idet i nogle tilfælde en gennem-ledning af nitrogen til fordrivelse af det dannede hydrogenhalogenid kan være på sin plads. I andre tilfælde er en tilsætning af dimethyl-formamid som reaktionskatalysator meget fordelagtig.

Enkeltheder angående fremstilling af mellemprodukterne med formlen II kan man få af de metoder, der alment anvendes til fremstilling af anilino-alkansyreestere, og som er angivet i følgende publikationsorganer: J.Org.Chem. 30, 4101 (1965), Tetrahedron 1967, 487, Tetrahedron 1967, 493· CH-j

Forbindelserne med formlen I med betydningen X = -*CH- har et asymmetrisk carbonatom (*) og kan på sædvanlig måde spaltes i optiske antipoder. Herved har den enantiomere D-form den stærkeste mikrobicide virkning.
Indenfor rammerne af opfindelsen foretrækkes følgelig de forbindelser med formlen I, der har D-konfiguration. Disse D-former har ved måling i ethanol eller acetone i reglen en negativ drejningsvinkel.
Til fremstilling af de rene optiske D-antipoder fremstilles f.eks. den racemiske forbindelse med formlen R1 2 3 4 R5 [ |H3 X -M-CH-C00H (VI) R^ -j n pr c hvori R , R , Br og R har den under formlen I nævnte betydning, 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 D-anti-pode berigede syre med formlen VI og eventuelt gentagelse (også flere ganges gentagelse) af saltdannelsen, krystallisationen og frigørelsen af α-anilinopropionsyren med formlen VI vinder man trinvis den rene D-form. Af denne kan man om ønsket på sædvanlig måde, f.eks. i nærværelse af HC1 eller HgSO^, med methanol eller ethanol fremstille den optiske D-konfiguration af den til grund for formlen II liggende ester eller med den tilsvarende amin med formlen HN(R")(R,n) det til formlen II svarende amid. Som optisk aktiv organisk base kommer f.eks. a-phenylethylamin på tale.
stedet for ved fraktioneret krystallisation kan den enantiomere D- 2 form med formlen VI også vindes ved udbytning af hydroxylgruppen i 3 den naturligt forekommende L(+)-mælkesyre med halogen og viderereak- 4 tion af dette produkt under konfigurationsomvendelse med den ønskede 5 anilin med formlen 6 141995 r5 R1 V^A.-nh2 (VII) R6/XI7

Uafhængigt af den optiske isomeri iagttages i reglen en atropisomeri om phenylaksen i de tilfælde, hvor phenylringen er substitueret mindst i 2,6-stilling og samtidig usymmetrisk til denne akse (eventuelt altså også ved tilstedeværelse af yderligere substituenter). Dette fænomen er betinget af den steriske hindring af de yderligere ved ΪΓ-atomet i anilinen med formlen VII indførte grupper -X-R^, men især af den heterocycliske gruppe -CO-R^. Såfremt der ikke gennemføres nogen målrettet syntese til isolering af rene isomere, fås normalt et produkt som blanding af to optiske isomere eller to atropisomere eller som blanding af disse fire mulige isomere. Den principielt 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.
De efterfølgende eksempler tiener til nærmere forklaring af opfindelsen. Såfremt ikke andet er angivet, menes ved omtalen af et virksomt stof med formlen I, der kan optræde i optisk aktive former, altid den racemi ske blanding.
