the conversion of allylic alcohols into the corresponding enantiomerically enriched cyclopropanes using bis(iodomethyl)zinc. A variety of chiral, nonracemic cyclopropylmethanols could be obtained according to this method. This methodology was extended with success to the cyclopropanation of unconjugated and conjugated polyenes and homoallylic alcohols. The cyclopropanation of allylic carbamates has also
已发现一种非常有效的手性控制剂,可使用双(碘甲基)锌将烯丙醇转化为相应的富含对映异构体的环丙烷。根据该方法可以获得多种手性、非外消旋环丙基甲醇。该方法成功地扩展到非共轭和共轭多烯和高烯丙醇的环丙烷化。烯丙基氨基甲酸酯的环丙烷化也已用该系统进行了研究,但发现富含对映体的环丙基甲基胺最好由富含对映体的环丙基甲醇制备。
