The present invention provides in one aspect a method of combating a fungus at a locus, characterised by treating the locus with a fungicidally effective amount of a compound of general formula I
wherein each of R' and R2 independently represents a hydrogen atom or an optionally substituted alkyl, alkenyl, alkynyl, aryl or aralkyl group; or an optionally substituted cycloalkyl, bicycloalkyl, cycloalkenyl or bicycloalkenyl group containing up to 12 ring atoms, in which at least one methylene group is optionally replaced by an oxygen atom or by a sulphone or sulphoxide group; or a group of general formula
in which m is 0 and p is 0 or 1, or m is 1 and p is 0, and RS is an optionally substituted alkyl, alkenyl, aryl or aralkyl group; or R' and R2 together with the interjacent carbon atoms form an optionally substituted cycloalkylene, bicycloalkylene, tricycloalkylene, cycloalkenylene, bicycloalkenylene or tricycloalkenylene group containing up to 18 ring atoms, in which at least one methylene group is optionally replaced by an oxygen or sulphur atom or by a sulphone or sulphoxide group; or an optionally substituted dihydronaphthylene, tetrahydronaphthylene, dihydrophenanthrylene or dihydroacenaphthylene group; each of R3 and R4 independently represents a hydrogen atom or an alkyl group or together represent a single chemical bond; or R' and R3 together with the interadjacent carbon atom form an optionally substituted cycloalkyl, bicycloalkyl, cycloalkenyl or bicycloalkenyl group containing up to 12 ring atoms, in which at least one methylene group is optionally replaced by an oxygen atom or a sulphone or sulphoxide group; provided that when R3 and R4 do not together represent a single chemical bond, at least one of R', R2, R3 and R4 is a hydrogen atom. Also certain of such compounds per se, and their preparation.
本发明的一个方面是提供了一种在基因座上防治真菌的方法,其特征在于用杀真菌有效量的通式 I 化合物处理基因座
其中,R'和 R2 各自独立地代表氢原子或任选取代的烷基、烯基、炔基、芳基或芳烷基;或任选取代的环烷基、双环烷基、环烯基或双环烯基,这些基团含有多达 12 个环原子,其中至少一个亚甲基任选被氧原子或砜基或亚砜基取代;或通式基团
其中 m 为 0,p 为 0 或 1,或 m 为 1,p 为 0,RS 为任选取代的烷基、烯基、芳基或芳烷基;或 R' 和 R2 与相邻碳原子一起形成任选取代的环亚烷基、双环亚烷基、三环亚烷基、环亚烯基、双环亚烯基或三环亚烯基,最多包含 18 个环原子,其中至少一个亚甲基任选被氧原子或硫原子或砜基或亚砜基取代;或任选取代的二氢萘基、四氢萘基、二氢菲基或二氢苊基;R3 和 R4 各自独立地代表一个氢原子或一个烷基,或共同代表一个单化学键;或 R' 和 R3 与相邻碳原子一起形成一个任选取代的环烷基、双环烷基、环烯基或双环烯基,其中最多包含 12 个环原子,其中至少一个亚甲基任选被一个氧原子或一个砜基或亚砜基取代;但当 R3 和 R4 不共同代表一个单化学键时,R'、R2、R3 和 R4 中至少有一个是氢原子。还包括某些此类化合物本身及其制备方法。
