High levels of enantioselectivity have been achieved in the diethylzinc addition to both aromatic and aliphatic aldehydes, employing readily available N-substituted-azetidinyl(diphenylmethyl)methanols as chiral catalysts.

Optically active amino thioacetate derivatives of (+l-norephedrine were found to act as effective catalysts for enantioselective addition of diethylzinc to aldehydes. This reaction provided optically active secondary alcohols with e.e. of up to >99%.
