A β-amino alcohol-Ti(Oi-Pr)4 complex efficiently catalyzes a mild, enantioselective cyanosilylation of aldehydes. Aromatic, conjugated, heteroaromatic, and aliphatic aldehydes were converted to their corresponding cyanohydrin trimethylsilyl ethers in excellent yields with high enantioselectivities.
