We herein report an enantioselective palladium-catalyzed cross-coupling between α-bromo carboxamides and aryl boronic acids, generating a series of chiral α-aryl carboxamides in good yields and excellent enantioselectivities. The development of a chiral P,P=O ligand was critical in overcoming the second transmetalation issue and allows the first asymmetric palladium-catalyzed coupling of α-bromo carbonyl compounds.
