  l-Threonine-Derived Novel Bifunctional Phosphine−Sulfonamide Catalyst-Promoted Enantioselective Aza-Morita−Baylis−Hillman Reaction

  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.
