具有光学活性的环丙烷衍生物可以由烯烃与手性卡宾或类卡宾试剂反应制得。应用手性钴或铜络合物催化剂于富电子烯烃与重氮化合物反应,可得到较高光学纯度的环丙烷衍生
Optically active cyclopropane derivatives can be obtained from the reaction of olefins with chiral carbenes or classcarbenes. The application of chiral cobalt or copper complex catalysts to the reaction of electron rich olefins with diazo compounds gives cyclopropane derivatives of higher optical purity
