Abstract
Experimental results are reported for the CuCl2-mediated asymmetric oxidati ve coupling of 2-naphthols in the presence of [-]alpha -methylbenzylamine t o optically active (S)-(-)-1,1'-bi-2-naphthol. Under anhydrous conditions a nd with a 3 : 1 molarity ratio of alpha -methylbenzylamine to 2-naphthol, a fair enantioselection has been observed(up to 80.6% ee).
