摘要
This work reported a convenient method for the preparation of enantiomerically pure 6-aryl-2,2'-dihydroxy-1, l'- binaphthyl derivatives starting from the commercially available (R)-2,2'-hydroxy-l, l'-binaphthyl [(R)-I] via bromi- nation, hydrolysis and Suzuki cross coupling reaction. This novel synthetie method was characterized with high re- gioselectivity, simple operation, mild reaction conditions, and excellent yield (up to 73%). On the other hand, we synthesized the target unknown compounds, which were confirmed by IR, 1H NMR, 13C NMR, MS and elementary analysis.
