自20世纪70年代初国内开展拟除虫菊酯杀虫剂开发研究工作,迄今已30余年,在这期间,菊酯类农药在全国有了很大发展,在农业生产上起到了重要作用,氯氰菊酯是拟除虫菊酯杀虫剂的重要品种之一,市场份额很大,本文对氯氰菊酯家族的系列产品作一综述。氯氰菊酯它是由二氯菊酸与氰醇(α-氰基间苯氧基苄醇)缩合的产品,在该产品化学结构中二氯菊酸部分三元环有二个手性碳原子,并且有顺反结构,而氰醇部分有一个手性碳原子,三个手性碳原子一共有8个异构体,分述如下: 1R3RαS(1R顺式αS) 1S3SαR(1S顺式αR) 1R3SαR(1R反式αR) 1S3RαS(1S反式αS)
Since the early 1970s, the domestic research and development on pyrethroid insecticides have been carried out for more than 30 years. During this period, pyrethroid pesticides have made great progress throughout the country and played an important role in agricultural production. Cypermethrin is Pyrethroid insecticides one of the important species, a large market share, this article on the family of cypermethrin products are reviewed. Cypermethrin It is a product of the condensation of dichloroquinic acid with cyanohydrin (α-cyano-m-phenoxybenzyl alcohol) in which part of the difluorochromate moiety has two chiral carbon atoms and There is a cis-trans structure, while the cyanohydrin part has a chiral carbon atoms, a total of three chiral carbon atoms eight isomers, are as follows: 1R3RαS (1R cis αS) 1S3SαR (1S cis αR) 1R3SαR 1R trans αR) 1S3RαS (1S trans αS)
