An efficient one-step synthesis of the optically active bifunctional BINOL ligand (S)-3 has been developed. It was found that (S)-3 in combination with Me(2)AICI is a highly enantioselective catalyst for the addition of TMSCN to aliphatic aldehydes of diverse structures and is also among the most practical ones. A remarkable positive nonlinear effect was found for this chiral ligand.
