Patent

CA 2293451

The invention relates to novel pesticidally active compounds of general formula (I) as well as possible isomers and mixtures of isomers thereof, wherein n is a number zero or one; and R1 is C1-C12alkyl that is unsubstituted or may be substituted by C1-C4alkoxy, C1-C4alkylthio, C1-C4alkylsulfonyl, C3- C8cycloalkyl, cyano, C1-C6alkoxycarbonyl, C3-C6alkenyloxycarbonyl or by C3- C6alkynyloxycarbonyl; C3-C8cycloalkyl; C2-C12alkenyl; C2-C12alkynyl; C1- C12haloalkyl; or a group NR11R12 wherein R11 and R12 are each independently of the other hydrogen or C1-C6alkyl, or together are tetra- or penta-methylene; R2 and R3 are each independently of the other hydrogen; C1-C8alkyl; C1-C8alkyl substituted by hydroxy, C1-C4alkoxy, mercapto or by C1-C4alkylthio; C3- C8alkenyl; C3-C8alkynyl; C3-C8cycloalkyl; C3-C8cycloalkyl-C1-C4alkyl; or the two groups R2 and R3 together with the carbon atom to which they are bonded form a three- to eight-membered ring; R4, R5, R6 and R7 are identical or different and are each independently of the others hydrogen or C1-C4alkyl; R8 is C1-C6alkyl, C3-C6alkenyl or C3-C6alkynyl; A is C1-C6alkylene; and B is optionally mono- or poly-nuclear, unsubstituted or substituted aryl; optionally mono- or poly-nuclear, unsubstituted or substituted heretoaryl; C4- C12alkyl; or C3-C8cycloalkyl. The novel compounds have plant-protecting properties and are suitable for protecting plants against infestation by phytopathogenic microorganisms.

La présente invention concerne de nouveaux composés à activité pesticide répondant à la formule générale (I), et les isomères et mélanges d'isomères possibles de ces derniers, formule dans laquelle n est égal à zéro ou à un; R¿1? est un alkyle C¿1?-C¿12? non substitué ou qui peut être substitué par un alcoxy C¿1?-C¿4?, un alkylthio C¿1?-C¿4?, un alkylsulfonyle C¿1?-C¿4?, un cycloalkyle C¿3?-C¿8?, un cyano, un alcoxycarbonyle C¿1?-C¿6?, un alkényloxycarbonyle C¿3?-C¿6? ou par un alyknyloxycarbonyle C¿3?-C¿6?; un cycloalkyle C¿3?-C¿8?; un alkényle C¿2?-C¿12?; un alkynyle C¿2?-C¿12?; un haloalkyle C¿1?-C¿12?; ou un groupe NR¿11?R¿12? dans lequel R¿11? et R¿12? sont chacun indépendamment de l'autre hydrogène ou alkyle C¿1?-C¿6?, ou ensemble tétra- ou penta-méthylène; R¿2? et R¿3? sont chacun indépendamment de l'autre hydrogène; alkyle C¿1?-C¿8?; alkyle C¿1?-C¿8? substitué par hydroxy, alcoxy C¿1?-C¿4?, mercapto ou par alkylthio C¿1?-C¿4?; alkényle C¿3?-C¿8?; alkynyle C¿3?-C¿8?; cycloalkyle C¿3?-C¿8?; cycloalkyle C¿3?-C¿8?-alkyle C¿1?-C¿4?; ou les deux groupes R¿2? et R¿3? forment ensemble avec l'atome de carbone auquel ils sont liés un noyau comprenant de 3 à 8 chaînons; R¿4?, R¿5?, R¿6? et R¿7? sont identiques ou différents et sont chacun indépendamment des autres hydrogène ou alkyle C¿1?-C¿4?; R¿8? est alkyle C¿1?-C¿6?, alkényle C¿3?-C¿6? ou alkynyle C¿3?-C¿6?; A est alkylène C¿1?-C¿6?; et B est facultativement un aryle mono- ou poly-nucléaire non substitué ou substitué; facultativement un hétéroaryle mono- ou poly-nucléaire non substitué ou substitué; un alkyle C¿4?-C¿12?; un cycloalkyle C¿3?-C¿8?. Ces nouveaux composés possèdent des propriétés de protection des plantes et ils sont aptes à protéger les plantes contre les infestations de micro-organismes phytopathogènes.
