the text. Notably, each member of the homologous series of amides Ph(CH2)nCONMe2 gives rise to a substantially different product: when n= 0, the reaction is normal, and the yield of the alph]-silylamine 20e is high; when n=1, proton transfer in the intermediate anion 64 and displacement of the phenyl group leads to the silaindane 66; when n=2, fragmentation of the intermediate anion 80, and capture

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).

developed for this transformation, allowing for the use of either aryl chlorides or bromides as electrophiles. Utilizing a highly electron‐rich dialkylphosphine ligand we have been able to construct α‐quaternary centers in good yields (up to 91 % yield) and high enantioselectivities (up to 97 % ee).
