Enantioselective carbene insertion into the N-H bond of benzophenone imine.


ABSTRACT: Efficient enantioselective insertion of ?-diazoesters into the N-H bond of N-sp2-hybridized benzophenone imine was realized by using Rh2(esp)2 and chiral guanidine cooperative catalysis. Both aliphatic and aromatic substituted ?-amino esters were obtained in high yields (up to 99%) and good enantioselectivities (up to 95.5?:?4.5 er) under mild reaction conditions.
