Abstract: Described here are transition metal-catalyzed enantioselective arylation and vinylation reactions of ?-substituted lactams, such as ?-lactams. The use of various electrophiles and ligands are described, and result in the construction of ?-quaternary centers in good yields (up to 91% yield) and high enantioselectivities (up to 97% ee).
