摘要
主要研究了硫、碲叶立德环丙烷化和环氧化反应的立体化学控制。通过添加剂、手性辅基、手性试剂等 3种策略,分别控制反应的非对映选择性和对映选择性。
Focusses on the stereoselective cyclopropanation of sulfonium and telluronium allylide with Michael acceptors. Three strategies (additive, chiral auxiliary or chiral reagent) were developed to improve the diastereoselectivity or enantioselectivity of the ylide cyclopropanation reactions. Some preliminary results of epoxidation reaction of sulfonium allylide were also included.
