摘要: 菊酸[2,2-二甲基3-(2-甲基丙烯基)环丙烷羧酸]是除虫菊酯类杀虫剂的重要中间体。在其分子中,相对于环丙烷平面存在顺、反异构体。由于环上有两个毛性碳原子,因而有4个旋光异构体。

Abstract: (±)-Cis-chrysanthemic acid 1 was resolved into (+)-1R-1 and(-)-1S-1 via the diastereomeric salts by using quinine as resolution reagent. Thus,the mixture of equimolar amount of (±)-1 and quinine was heated in EtOH-H2O(4:1 V/V) to have been solved cmpletely and was allowed to standundisturbed in a water bath at, 43~35℃ for 12~16h. The fine needles obtainedwere recrystallized.
