Copper-Bipyridine-Catalyzed Enantioselective α-Amination of β-Keto Esters. — Highly enantioselective α-amination of 1-indanone-based β-keto esters with diethyl azodicarboxylate is achieved in the presence of a chiral copper-bipyridine catalyst. Interestingly, β-diketones react with significant lower enantioselectivity under similar conditions. — (GHOSH, S.; NANDAKUMAR, M.
