摘要：

Enantioselective reaction of benzaldehyde 4-anisidineimine 1 with methyllithium in toluene was mediated by a series of chiral aminoethers 3-11 to give the corresponding amine 2 in good to moderate ee. The chiral tridentate aminoethers 7-11 are superior to the bidentate ligands 3-6, Lithium bromide affects significantly the enantioselectivity in the catalytic reaction, but not in the stoichiometric reaction.
