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