Patent
CA 2421839
The invention relates to a method for producing anellated tetrahydro-[1H]- triazoles of formula I wherein the variables Ra, Z, Z1, X, W, n and Q have the designations cited in patent claim 1, by cyclising compounds of general formula II wherein R represents C(X)OR2 or C(X)SR2, X represents oxygen or sulphur, and R2 has the designation cited in patent claim 1, in the presence of a base. The invention also relates to compounds of general formula I wherein W represents sulphur if Z represents a methylene group which is optionally substituted by Ra, as well as other compounds of formula I wherein Q represents a benzoxazole or benzothiazole radical. The invention further relates to the uses of said compounds as herbicides.
La présente invention concerne un procédé de préparation de tétrahydro-[1H]-triazoles de formule I, les variables R?a¿, Z, Z?1¿, X, W, n et Q ayant les significations spécifiées dans la revendication 1, par cyclisation de composés de formule générale II, R désignant C(X)OR?2¿ ou C(X)SR?2¿, X désignant oxygène ou soufre et R?2¿ ayant la signification spécifiée dans la revendication 1, en présence d'une base. L'invention concerne également des composés de formule générale I, W désignant soufre si Z désigne un groupe méthylène substitué le cas échéant par R?a¿, ainsi que d'autres composés de formule I, Q désignant un reste benzoxazole ou benzothiazole, et des utilisations de ces composés en tant qu'herbicides.
