Description
DK 164151 B
Den foreliggende opfindelse angår et plantefungicid, der som aktiv bestanddel indeholder et N-pyridylcarbamatderivat, og en fremgangsmåde til beskyttelse af planter mod fungusinfektioner.
Der findes mange fungicider, som anvendes i vid udstrækning og bidra-5 ger til afgrødebeskyttelse og forøgelse af afgrødeudbyttet. Imidlertid har udviklingen af nye landbrugsmæssige fungicider med udmærkede fungicide virkninger og tilsvarende stor praktisk værdi været et område af stor betydning.
GB patentskrift nr. 967.897 beskriver forbindelsen 2-naphthyl-N-(2-10 pyridyl)-N-methyl-thiocarbamat og angiver generelt, at de i patentskriftet omhandlede forbindelser er nyttige landbrugsfungicider. Forbindelserne ifølge opfindelsen har obligatorisk som substituent en alkyl-, alkoxy-, alkenyloxy- eller alkylaminogruppe på pyridinringen og er i denne henseende forskellige fra den ovennævnte pyridinring-15 holdige forbindelse, der er beskrevet i GB patentskriftet. Denne forskel er af væsentlig betydning; det fremgår af eksempel 8, at forbindelsen 2 ifølge opfindelsen har en langt kraftigere plantefungicid virkning end den kendte forbindelse.
FR 2220191 beskriver fungicidt virkende carbamater, der er -NH- deri-20 vater, dvs. kun har en pyridylgruppe som substituent på nitrogenatomet. Forbindelserne ifølge den foreliggende opfindelse er N-alkyl-N-pyridylderivater, der altid foruden pyridylgruppen har en lavere alkylgruppe Z som substituent på nitrogenatomet. Desuden er forbindelserne ifølge FR 2220191 0-alkyl-carbamatderivater med en lavere 25 alkylgruppe som alkoholresten R, medens forbindelserne ifølge den foreliggende opfindelse er 0-aryl-carbamatderivater med forskellige bestemte aromatiske grupper, såsom 2-naphthyl eller phenyl, som gruppen X. Alt i alt er der således med forbindelserne ifølge opfindelsen tale om forbindelser, der er væsentligt forskellige fra de 30 fra FR 2220191 kendte forbindelser.
Fra GB patentansøgning nr. 2.138.804 kendes N-substituerede plante-fungicide carbamater, der er substitueret med en phenylgruppe på carbamatnitrogenatomet. I modsætning hertil er forbindelserne ifølge den foreliggende opfindelse sådanne med en substitueret pyridylgruppe
DK 164151 B
2 på carbamatnitrogenatomet. Blandt de forbindelser, der er beskrevet i GB patentansøgning nr. 2.138.804, er der kun en enkelt, som er et N-alkyl-N-phenylderivat, og dette derivat har en usubstitueret phenyl-gruppe som alkoholresten. I de tilfælde, hvor forbindelserne ifølge 5 opfindelsen har en phenylgruppe som alkoholrestgruppe X, er denne phenylgruppe obligatorisk substitueret. Ganske vist beskriver GB patentansøgning nr. 2.138.804 eksempler på forbindelser, der har en substitueret phenylgruppe som alkoholrestgruppe Rj_, men de pågældende forbindelser er så -NH- derivater, altså forbindelser, som ikke har 10 nogen alkylgruppe på carbamatets nitrogenatom. Forbindelserne ifølge opfindelsen er N-alkyl-N-pyridylderivater, som obligatorisk, ud over en substitueret pyridylgruppe, har en lavere alkylgruppe Z på nitrogenatomet. Alt i alt er der således med de fra GB patentansøgning nr. 2.138.804 kendte carbamater tale om forbindelser, der i kemisk hen-15 seende er væsentligt forskellige fra forbindelserne ifølge opfindelsen.
Den foreliggende opfindelse angår et plantefungicid, der er ejendommeligt ved, at det omfatter 1) en biologisk inert bærer, 2) som aktiv bestanddel en virksom mængde af et N-pyridylcarbamatderivat med 20 den almene formel I

Fremgangsmåden ifølge opfindelsen er ejendommelig ved, at planterne påføres en virksom mængde af et N-pyridylcarbamatderivat med den almene formel I.
N-Pyridylcarbamatderivaterne med den almene formel I, som udgør den 5 aktive bestanddel i plantefungicidet, er kendte forbindelser med herbicid virkning, jfr. US patentskrift nr. 4.554.012 og EP 90263A1, og kan fremstilles i overensstemmelse med nedenstående reaktionsskema Y Z Y z X - OH + Hal - C- N- W-*X-0-C-N-W (1)...(1)

De ovenfor viste reaktioner forløber i nærværelse af dehydrohalogene-ringsmidler og endvidere i nærværelse eller fraværelse af et reaktionsopløsningsmiddel, sædvanligvis ved en reaktionstemperatur på 0-150°C med en reaktionstid på fra adskillige minutter til 48 timer. 1
Dehydrohalogeneringsmidlerne omfatter alkalimetalhydroxider såsom natriumhydroxid, kaliumhydroxid og lignende, jordalkalimetalhydroxider såsom calciumhydroxid og lignende, alkalimetalcarbonater såsom natriumcarbonat, kaliumcarbonat, natriumhydrogencarbonat, kalium-hydrogencarbonat og lignende, tertiære aminer såsom triethylamin,

4 dimethylanilin, pyridin og lignende. I reaktionsskema 2) kan udgangs-aminopyridinderivatet anvendes som dehydrohalogeneringsmiddel.
De reaktionsopløsningsmidler, der kan anvendes i de med 1) og 2) angivne reaktioner, omfatter vand, alkoholer såsom methanol, ethanol, 5 isopropanol og lignende, ketoner såsom acetone, methylethylketon og lignende, aromatiske carbonhydrider såsom benzen, toluen, xylen og lignende, ethere såsom ethylether, tetrahydrofuran, dioxan og lignende, halogenerede carbonhydrider såsom chlorbenzen, chloroform, carbontetrachlorid, dichlorethan og lignende, polære opløsningsmidler 10 såsom dimethylformamid, dimethylsulfoxid og lignende.
Fremgangsmåden til fremstilling af N-pyridylcarbamatderivaterne med den almene formel I forklares nærmere i følgende specifikke eksempler.
Eksempel på syntese 1 15 Syntese af 0-4-brom-3-ethylphenyl-N-(6-methoxy-2-pyridyl)-N-methyl-thiocarbamat (forbindelse nr. 5)
Til en blanding af 1,38 g 2-methoxy-6-methylaminopyridin og 1,38 g vandfrit kaliumcarbonat i 20 ml acetone sattes dråbevis 2,80 g 0- 4-brom-3-ethylphenylchlorthioformiat i 20 ml acetone under omrøring 20 ved stuetemperatur. Den resulterende blanding blev omrørt i 30 minutter ved stuetemperatur og derefter underkastet tilbagesvaling i 2 timer. Efter at reaktionsblandingen var afkølet til stuetemperatur, blev uorganiske salte fjernet ved filtrering, og acetone blev fjernet ved destillation. Remanensen blev oprenset ved søjlechromatografi 25 (silicagel, benzen), hvilket gav 2,78 g af titelforbindelsen. En del af produktet blev omkrystalliseret af benzen/hexan, hvilket gav farveløse krystaller med et smeltepunkt på 84-85eC.

Syntese af 3-tert.butyl-4-chlorphenyl-N-(6-methoxy-2-pyridyl)-N-methylcarbamat (forbindelse nr. 56)
En blanding af 2,01 g N-(6-methoxy-2-pyridyl)-N-methylcarbamoylchlo-5 rid, 1,85 g 3-tert.butyl-4-chlorphenyl og 1,38 g vandfrit kaliumcar-bonat i 30 ml acetone blev opvarmet under tilbagesvaling i 24 timer.
Efter at reaktionsblandingen var afkølet til stuetemperatur, blev uorganiske salte fjernet ved filtrering, hvorefter acetone blev fjernet ved destillation under reduceret tryk. Remanensen blev oprenset 10 ved søjlechromatografi (silicagel, benzen), hvilket gav 3,13 g af titelforbindelsen. En del af produktet blev omkrystalliseret af hexan, hvilket gav farveløse krystaller med et smeltepunkt på 54-56°C.
