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.
Key words： ylide; cyclopropanation; epoxidation; diastereoselectivity; enantioselectivity
