摘要
Atropisomeric anilides are one of important C-N axially chiral compounds.Compared with the A/-terminal functionalization to prepare such compounds,C-terminal functionalization strategies have been rarely reported.We describe herein an efficient synthesis of axially chiral anilides enabled by Pd-catalyzed desymmetric Sonogashira cross-coupling reactions with the use of a newly identified Ming-Phos.Moderate to high yields with high enantioselectivities(up to 98%ee)were obtained.
