A H8-binol derived catalyst allows high enantioselectivity in the reaction of diphenylzinc with both aliphatic and aromatic aldehydes. The use of this catalyst avoids the need for additives such as diethylzinc and the mild asymmetric reaction conditions make this chiral catalyst useful for general synthesis.
