Asymmetric epoxidation of chalcone catalyzed by chiral (5)‐6, 6′‐diphenyl‐BINOL‐lanthanum complex affords the corresponding epoxychalcone with excellent yields as well as the good enantioselective excesses of 93%. The influences of solvent, the temperature, the structure of the chiral ligand, as well as the substrate on the stereochemistry were discussed.
