Fund Project:

Enantioselective chlorination of β-keto esters and amides catalyzed by squaramide-linked bisoxazoline ligand-Cu(OAc)₂ complexes was investigated. The corresponding chlorinated products were obtained in excellent yields with moderate enantioselectivities. The effect of solvent, temperature, Lewis acid, and ligand structure on the reaction is discussed. This was the first investigation of catalytic asymmetric α-chlorination of β-keto amides. This study has highlighted that a simple chiral squaramide-oxazoline with cheap Cu(OAc)₂·H₂O complexes can catalyze this chlorination.
