Efficient enantioselective insertion of α-diazoesters into the N-H bond of -sp-hybridized benzophenone imine was realized by using Rh(esp) and chiral guanidine cooperative catalysis. Both aliphatic and aromatic substituted α-amino esters were obtained in high yields (up to 99%) and good enantioselectivities (up to 95.5 : 4.5 er) under mild reaction conditions.
通过使用Rh(esp)和手性胍协同催化，实现了α-重氮酯高效对映选择性插入到sp杂化二苯甲酮亚胺的N-H键中。在温和的反应条件下，脂肪族和芳香族取代的α-氨基酯均以高收率（高达99%）和良好的对映选择性（高达95.5:4.5的对映体过量）得到。
