α—氰基—3—苯氧基苄基α—(4—氯苯基)异戊酸酯(Fenvalerate S—5602 Sumicidin~((R))是一种新的合成拟除虫菊酯杀虫剂。其分子中酸和醇的部位都有不对称的碳原子。因此,S—5602是四个立体异构酯的混合物,而其酸部分中S—构型的杀虫力比R—构型的强。本文介绍了 S—5602酸部分旋光异构体的分析方法。关于丙烯菊酯、二氯苯醚菊酯及其他菊酸酯类的光学异构体的分析方法,已有报导。在研究中是将酯在碱液中水解生成的酸或醇衍生为非对映异构体的酯,用气相色谱测定。虽然这些方法可以应用于 S—5602,但在碱液中水解时,释放出的α—4—氯苯基异 Fenvalerate S-5602 Sumicidin (R) is a new synthetic pyrethroid insecticide. S-5602 is a mixture of four stereoisomeric esters, and the S-configuration in its acid moiety is more biocidal than the R-configuration The method for the analysis of acid-part optical isomers of S-5602 has been described in this paper.Analytical method of optical isomers of alprustine, permethrin and other chrysanthemate esters has been reported.In the study Is an ester of an acid or alcohol derived from the hydrolysis of an ester in a lye and is derivatized as a diastereomer and determined by gas chromatography. Although these methods are applicable to S-5602, they are released upon hydrolysis in a lye Of alpha-4-chlorophenyl iso
