Optically active binaphthols bearing substituents at the 6,6-positions were synthesized by the base reaction of 6,6'-dihydroxyl-2,2'-binaphthol and the dendritic benzyl bromides. Despite the bulky dendritic substituents, the dendritic binaphthols were found to from metal complexes and catalyze asymmetric C-C bond forming reactions.
