Optically active set-alcohols in 90% enantiomeric excess were obtained from the enantioselective addition of dialkyl zincs to aryl aldehydes in the presence of a catalytic amount of dilithium salt of (2S, 52)-2, 5diisopropylpiperazine. Chiral piperazine (cyclic diamine) has rarely been utilized as c
