A novel procedure for selective direct N,N-alkylation of the chiral Betti base was developed, and a new family of chiral ligands, (S)-1-(a-cycloaminobenzyl)-2-naphthols, were prepared. The ligands with five-and six-membered cyclic amines showed highly efficient asymmetric induction in the addition o
