Abstract

Herein, we report the first Pd‐catalyzed enantioselective arylation of α‐substituted γ‐lactams. Two sets of conditions were 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).
