no]acetates with quaternary stereocenters and potential antibacterial activities were obtained in excellent yields with good to excellent ee values under as low as 0.05 mol % catalyst loading. The products could be easily transformed to useful α‐amino amides and 1,2‐diamines. Besides, a possible transition state model was proposed to elucidate the origin of the chirality induction.
