Description

Opfindelsen angår nye, værdifulde N-3'-(p-tert.-bu-tylphenyl)-2'-methyl-propyl-1'-piperidinderivater og deres salte med god fungicid virkning, fungicider, der indeholder disse forbindelser, og en fremgangsmåde til 5 bekæmpelse af svampe med disse forbindelser.
Det er kendt at anvende N-3'-(p-tert.-butylphenyl)-2 methyl-propyl-1'-3-hydroxymethylpiperidin som fungicid (DE-OS 27 27 482). Det er også kendt at anvende N-3'-(p-10 tert.-butylphenyl)-2'-methylpropyl-l,-piperidin og det tilsvarende -4-hydroxypiperidin som fungicider (DE-OS 2 752 135).
Forbindelserne ifølge opfindelsen er estere af N-3'-(p-15 tert.butylphenyl)-2'-methyl-propyl-1'-3-hydroxymethyl- piperidin med den i krav 1 angivne formel. Det har vist sig, at disse forbindelser har en god fungicid virkning, som er overlegen i forhold til den fungicide virkning af den kendte hydroxyforbindelse.
20
Salte er f.eks. saltene med uorganiske eller organiske syrer, f.eks. chlorider, fluorider, bromider, iodider, sulfater, nitrater, phosphater, acetater, propionater eller med syrer af tensider, f.eks. dodecylbenzensulfon-25 syre.
Fremstillingen af forbindelserne ifølge opfindelsen foregår f.eks. ved omsætning af 3-hydroxymethyl-piperidin med 3-p-tert.-butyl-phenyl-2-methylpropanal i nærværelse 30 af et reduktionsmiddel, f.eks. myresyre ved temperaturer fra 50 til 110 °C og forestring af hydroxyforbindelsen med acetanhydrid eller propionsyreanhydrid på sædvanlig måde.

De følgende eksempler illustrerer fremstillingen af de nye forbindelser.
Udgangsforbindelserne kan fremstilles på følgende måde.

Forskrift 1
Syntese af N-3'-(p-tert.-butylphenyl)-2'-methyl-propyl-1'-3-hydroxymethyl-piperidin.
10 I en 1 liter kolbe indføres 204 g 3-(4'-tert.-butyl-phe-nyl-1')-2-methylpropanol og under omrøring tilsættes 115 g 3-hydroxymethylpiperidin. Under afkøling tilsættes derpå 50 g 98% myresyre. Chargen bliver derpå opvarmet 15 til kogning, og derved indtræder der en stærk dannelse af CC>2. Efter 12 timers opvarmning til 120 til 140 °C er syntesen afsluttet.
Til rensning af produktet destillerer man under et tryk 20 på 3 mbar. Efter et forløb på 44 g, der går over indtil en temperatur på 169 °C/3 mbar, og som i henhold til den gaschromatografiske analyse (GC) indeholder 27% af slutproduktet, går der 260 g slutprodukt over mellem 169 og 174 °C. I henhold til GC-analysen foreligger der et ca.
25 95% rent produkt. Udbytterne i forhold til de to ud gangsprodukter andrager 84%. NMR-analysen viser de forventede signaler.

Eksempel 1
Syntese af N-3'-(p-tert.-butylphenyl)-2'-methyl-propyl-l'-3-acetoxymethyl-piperidin (I) 5 I en 250 ml rundkolbe indføres 30 g N-3'-(p-tert.-butyl-pheny1)-2'-methy1-propy1-1'-3-hydroxymethylpiper idin, og der tilsættes 50 g acetanhydrid. Som katalysator til forestringen tildryppes 1 ml pyridin. Med henblik på 10 fuldstændig omsætning opvarmes reaktionsblandningen i 20 minutter under tilbagesvaling. Med henblik på rensning af produktet I destillerer man reaktionsblandingen ved 3 mbar. Indtil en temperatur af 153 °C går 10 g over (56% renhed i henhold til GC-analyse). Hovedmængden af pro-15 dukt I går over mellem 153 og 155 °C. I henhold til GC-analysen foreligger der et produkt med 99% renhed. NMR-analysen viser de forventede signaler.

Rensningen foregår ligeledes ved destillation under et tryk på 3 mbar. Der går 24 g produkt II over i temperaturområdet mellem 169 og 172 °C ved 3 mbar. I henhold til GC-analy-sen foreligger der et produkt, der har en renhed på over 35

De aktive stoffer ifølge opfindelsen og de hermed fremstillede fungicider er især velegnet til bekæmpelse af plantesygdomme, f.eks. Erysiphe graminis (ægte meldug) i korn, Erysiphe cichoracearum (ægte meldug) i græskar-10 planter, Podosphaera leucotricha i æbler, Onicinula ne-cator i vin, Erysiphe polygoni i bønner, Sphaerotheca pannosa i roser, Microshpaera querci i eg, Botrytis ci-nera i jordbær, vin, Mycosphaerella muscola i bananer, Puccinia-arter (rustsvampe) i korn, Uromyces appendicu-15 latus og u.phaseoli i bønner, Hemileia vastratrix i kaffe og Rhizoctonia solani. De er systemisk aktive; de optages både via roden og via bladene og transporteres i plantevævet.
20 Ved anvendelsen af de nye aktive stoffer til behandling af planter mod svampeinfektioner ligger de anvendte mængder mellem 0,025 og 5 kg aktivt stof/ha overflade.
Med henblik på overfladebeskyttelse af træer og frugter kan det aktive stof også anvendes i forbindelse med 25 formstofdispersioner i en koncentration af 0,25% til 5%, beregnet i forhold til dispersionens vægt. Fungiciderne indeholder i almindelighed mellem 0,1 og 95 vægt-% af det aktive stof, fortrinsvis mellem 0,5 og 90%. Det aktive stof kan blandes med andre kendte fungicider. I 30 mange tilfælde opnår man derved en forøgelse af det fungicide virkningsspektrum? ved et antal fungicidblandinger i vægtforholdene 1:10 til 10:1 optræder der også synergistiske virkninger, dvs. den fungicide aktivitet af kombinationsproduktet er større end de adderede fun-35 5
