Dichlorocarbene generated from chloroform and aqueous sodium hydroxide using chiral tertiary amines as a catalyst adds enantioselectively to olefins to give chiral dichlorocyclopropane derivatives. Optical rotations of the products strongly depend on the structure of catalysts employed.
使用手性叔胺作为催化剂,由氯仿和氢氧化钠水溶液生成的二氯卡宾与烯烃对映选择性加成,得到手性二氯环丙烷衍生物。产物的旋光度很大程度上取决于所用催化剂的结构。
