摘要

A fungicidal compound having general formula (I), wherein R<1> is a N-or C-linked 5-membered heterocyclic ring containing from 2 to 4 heteroatoms selected from N, O and S, at least one of which is N, and which is optionally N- or C-substituted with one or more of halo, C1-6 alkyl, halo(C1-6)alkyl, C1-4 alkoxy(C1-6)alkyl, aryl(C1-6)alkyl, C1-6 alkoxy, halo(C1-6)alkoxy, C1-6 alkylthio, C1-6 alkylcarbonyl, C1-6 alkylcarbonylamino, C1-6 alkoxycarbonyl, arylcarbonyl, aryl, aryloxy, or heteroaryl, the aryl and heteroaryl substituents themselves being optionally substituted with one or more of halo, C1-6 alkyl, halo(C1-6)alkyl, C1-6 alkoxy, halo(C1-6)alkoxy, C1-4 alkoxy(C1-6)alkyl, nitro, amino, mono- or di(C1-4)alkylamino, cyano, C1-6 alkoxycarbonyl or C1-6 alkylcarbonyl, and R<2> is phenyl, pyridyl, pyrimidinyl, pyridazinyl, pyrazinyl, triazinyl, pyrrolyl, furyl, thienyl, pyrazolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, triazolyl, thiadiazolyl, oxadiazolyl or tetrazolyl, any of which is optionally substituted with one or more of halo, C1-6 alkyl, halo(C1-6)alkyl, C1-6 alkoxy, halo(C1-6)alkoxy, C1-6 alkylthio, nitro, cyano, thiocyanato, C1-4 alkylsulphonyl, halo(C1-4)alkylsulphonyl, aminosulphonyl or C1-6 alkoxycarbonyl or, two adjacent substitutents join to form with the carbon atoms to which they are attached a fused benzene ring optionally substituted with halo, C1-4 alkyl or C1-4 alkoxy.
