Patent

CA 2050352

A heterocyclic compound having structural formula (I), where R is C1-C8 alkyl, C3-C6 cycloalkyl, trifluoromethyl, phenyl, substituted phenyl, phenoxy, substituted phenoxy, benzyl or substituted benzyl; and R1 is at least a partially saturated monocyclic or bicyclic heterocycle of nitrogen which may be substituted with lower alkyl and physiologically acceptable salts thereof is disclosed. A process for forming this compound which involves the reaction of an amine of the formula HR1 where R1 has the meanings given above with a substituted 2-propenyl halide having structural formula (II), where R has the meanings given above; and X is a halogen atom is described. The invention embodies the above-mentioned novel 2-propenyl halide utilized as an intermediate in the formation of the heterocyclic compound of this invention. A method of controlling phytopathogenic fungi by applying a fungicidally effective amount of the heterocyclic compound of the present invention to the locus under attack by said fungi is also taught. Finally, a fungicidally composition comprising the heterocyclic compound of the present invention and a suitable carrier therefor is set forth.

L'invention concerne un composé hétérocyclique ayant la formule structurelle (I), dans laquelle R représente alcoyle C1-C8, cycloalcoyle C3-C6, trifluorométhyle, phényle, phényle substitué, phénoxy, phénoxy substitué, benzyle ou benzyle substitué; et R1 représente au moins un hétérocycle monocyclique ou bicyclique au moins partiellement saturé, d'azote, pouvant être remplacé pare l'alcoyle inférieur et ses sels physiologiquement acceptables. L'invention concerne également un procédé de formation dudit composé consistant en la réaction d'une amine de la formule HR1 dand laquelle R1 est défini tel que ci-dessus, avec un halogénure de 2-propényle substitué ayant la formule structurelle (II), dans laquelle R est défini tel que ci-dessus; et X représente un atome d'halogène. L'invention met en oeuvre le nouvel halogénure de 2-propényle utilisé comme intermédiaire dans la formation du composé hétérocyclique de l'invention. L'invention concerne en outre un procédé de régulation de champignons phytopathogéniques par application d'une quantité fongicide efficace du composé hétérocyclique de l'invention à l'endroit subissant une attaque par lesdits champignons. Enfin, on a mis au point une composition fongicide comprenant le composé hétérocyclique de l'invention, ainsi qu'un support adapté à celui-ci.
