摘要

A series of novel bifunctional phosphine− sulfonamide organic catalysts were designed and readily prepared from natural amino acids, and they were utilized to promote enantioselective aza-Morita− Baylis− Hillman (MBH) reactions. l-Threonine-derived phosphine− sulfonamide 9b was found to be the most efficient catalyst, affording the desired aza-MBH adducts in high yields and with excellent enantioselectivities.
