Document Type and Number:
WIPO Patent Application WO1999014202
Kind Code:
B1
Abstract:
Novel pyrimidin-4-one and pyrimidin-4-thione derivatives of formula (I) wherein A is phenyl, thienyl (including all 3 isomers), thiazolyl, pyridyl or pyridazinyl; X is oxygen or sulfur; R1 is hydrogen, halogen or trimethylsilyl; R2 is hydrogen, halogen or trimethylsilyl; at least one of R1 and R2 is not hydrogen; R3 is C1-C8alkyl, C1-C8alkenyl, C1-C8alkinyl which are unsubstituted or mono to tri-substituted by C3-C6cycloalkyl, halogen, C1-C6alkoxy or C1-C6haloalkoxy; O-C1-C6alkyl, O-C2-C6alkenyl, O-C2-C6alkynyl, which are unsubstituted or mono to tri-substituted by C3-C6cycloalkyl, halogen or C1-C6alkoxy; N-C1-C6alkyl; or N=CHC1-C6alkyl; R4 is C1-C8alkyl, C1-C8alkenyl, C1-C8alkinyl which are unsubstituted or mono to tri-substituted by C3-C6cycloalkyl, halogen, cyano, C1-C6alkoxy or C1-C6haloalkoxy; C1-C4alkoxy-C1-C4alkoxy; C1-C4alkoxy-C1-C4alkylthio; nitro; -CO-C1-C6alkyl; C3-C6cycloalkyl; or phenyl, which is unsubstitued or mono to tri-substituted by halogen, C1-C6alkyl, C1-C6haloalkyl, C1-C6alkoxy, C1-C6haloalkoxy, cyano, nitro, amino, mono-C1-C6alkylamino, di-C1-C6alkylamino, C1-C6alkylthio, phenyl or phenoxy and in which the phenyl part is unsubstituted or mono to tri-substituted by halogen, C1-C6alkyl, C1-C6haloalkyl, C1-C6alkoxy or C1-C6haloalkoxy. The novel compounds have plant-protective properties and are suitable for protecting plants against infestation by phytopathogenic microorganisms, in particular fungi.
