CA 2477931

A compound of formula (I): F1 Het is a 5- or 6-membered heterocyclic ring containing one to three heteroatoms, each independently selected from oxygen, nitrogen and sulphur, the ring being substituted by groups R4, R5 and R6; R1 is hydrogen or halo; R2 is hydrogen or halo; R3 is optionally substituted C2- 12 alkyl, optionally substituted C2-12 alkenyl, optionally substituted C2-12 alkynyl, optionally substituted C3-12 cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl; and R4, R5 and R6 are, independently, selected from hydrogen, halo, cyano, nitro, C1-4 haloalkyl, C1- 4 alkoxyl (C(1-4) alkoxyl (C1-4) alkyl and C1-4 haloalkoxy (C1-4) alkyl, provided that at least one of R4, R5 and R6 is not hydrogen. The compounds of formula (I) have plant-protective properties and are suitable for protecting plants against infestations by phytopathogenic microorganisms.

L'invention concerne un composé de la formule (I), dans laquelle Het représente un noyau hétérocyclique à 5 ou 6 éléments contenant un ou trois hétéroatomes, chacun choisi indépendamment parmi oxygène, azote et soufre, leur noyau étant substitué par les groupes R?4¿, R?5¿ et R?6¿; R?1¿ représente hydrogène ou halo; R?2¿ représente hydrogène ou halo; R?3¿ représente alkyle C¿2-12? éventuellement substitué, alcényle C¿2-12? éventuellement substitué, alkynyle C¿2-12? éventuellement substitué, cycloalkyle C¿3-12? éventuellement substitué, phényle éventuellement substitué ou hétérocyclyle éventuellement substitué; et R?4¿, R?5¿ et R?6¿ sont indépendamment choisis parmi hydrogène, halo, cyano, nitro, alkyle C¿1-4?, haloalkyle C¿1-4?, alcoxy C¿1-4?(C¿1-4?)alkyle et haloalcoxy C¿1-4?(C¿1-4?)alkyle, pour autant qu'au moins un R?4¿, R?5¿ et R?6¿ ne soit pas hydrogène. Les composés de la formule (I) présentent des propriétés phytoprotectrices et conviennent pour protéger les plantes contre des infestations de microorganismes phytopathogènes.
