Bidentate ligand-catalyzed enantioselective addition of RZnX to benzaldehyde

Abstract Enantioselective addition of RZnX (R = alkyl, X = Cl, OAc) was studied using chiral chelating agents, particularly metal-alkoxides. Moderate enantioselectivity was achieved in the presence of magnesium-TADDOLate using RZnOAcMg(OAc)Br as the alkylating agent.
