Abstract: Axially chiral enamides bearing a N–C axis have been recently studied and were proposed to be valuable chiral building blocks, but a stereoselective synthesis has not been achieved. Here, we report the first enantioselective synthesis… read more here.

Abstract: Herein, we report the catalytic asymmetric synthesis of a unique family of axially chiral enamides in good yields with excellent enantioselectivities under mild conditions. These new axially chiral compounds feature a flexible skeleton and a… read more here.
