4-heteroaroylisoxazole derivatives of formula I:
wherein:
Ar represents an optionally substituted group Het, wherein Het represents a first heterocyclic ring containing from one to four heteroatoms in the ring selected from oxygen, nitrogen and sulphur, which is optionally fused with a benzene, or carbocyclic or second heterocyclic ring (which is optionally saturated or partially saturated) to form a bicyclic system, wherein the first heterocyclic ring of the group Het is attached to the carbonyl group in the 4-position of the isoxazole ring;
R represents hydrogen or -CO₂R³;
R¹ represents alkyl or haloalkyl or a cycloalkyl group optionally substituted by one or more groups R⁴;
R³ and R⁴ independently represent alkyl or haloalkyl;
agriculturally acceptable salts thereof and their use in weed control is described.
式 I 的 4-杂戊酰异噁唑衍生物:
其中
Ar 代表任选取代的基团 Het,其中 Het 代表第一杂环,环中含有一至四个杂原子,选自氧、氮和硫,可任选与苯、或碳环或第二杂环(可任选饱和或部分饱和)融合形成双环体系,其中基团 Het 的第一杂环连接到异噁唑环 4 位的羰基上;
R 代表氢或-CO₂R³;
R¹ 代表烷基或卤代烷基或任选被一个或多个基团 R⁴ 取代的环烷基;
R³和R⁴各自代表烷基或卤代烷基;
描述了其农业上可接受的盐类及其在除草中的用途。
