An efficient and enantioselective bromolactonization of 1,2-disubstituted olefinic acids using an amino-thiocarbamate catalyst has been developed, resulting in the formation of δ-lactones containing two chiral centers with up to 99% yield, 95% ee.
已经开发出使用氨基-硫代氨基甲酸酯催化剂对1,2-二取代的烯烃进行有效和对映选择性的溴内酯化,从而形成了包含两个手性中心的δ-内酯,产率高达99%,ee为95%。
