An aluminum complex was found to be high yielding and enantioselective for the addition of cyanide to aldimines and ketimines. The present catalyst provides uniformly high enantioselectivity for aromatic, heteroaromatic, and aliphatic aldimines and ketimines using ethyl cyanoformate as the cyanide source.
