摘要
Highly diastereo- and enantioselective aldol-type reactions of a silyl enol ether with aldehydes including aromatic, aliphatic, and alpha,beta-unsaturated ones are performed in propionitrile (solvent) by the use of a catalytic amount of chiral tin(II) Lewis acid consisting of tin(II) triflate and a chiral diamine. The asymmetric environments created by the chiral catalysts in the enantioselective aldol reaction are discussed by employing five kinds of chiral diamines.
