A series of new chiral amide ligands were prepared from natural amino acids and applied to the copper-catalyzed asymmetric oxidative homocoupling reaction of 3-hydroxy-2-naphthoates. By optimizing the reaction conditions, it was found that when using L3 (5 mol%) as the ligand, CuCl (5 mol%) as the catalyst, dichloromethane as the solvent, 2,2,6,6-tetra- methylpiperidine 1-oxyl (TEMPO)/O₂ as the oxidant, and under the reaction condition of 40 ℃, this method exhibited good substrate tolerance. Under these conditions, a series of chiral 1,1'-bi-2-naphthol (BINOL) derivatives were synthesized with yields of 45%~90% and enantioselectivities ranging from 50∶50 to 97∶3.
