An iron-catalyzed asymmetric oxidative homo-coupling of 2-naphthols for the synthesis of 1,1'-Bi-2-naphthol (BINOL) derivatives is reported. The coupling reaction provides enantioenriched BINOLs in good yields (up to 99%) and moderate enantioselectivities (up to 81:19 er) using an iron-complex generated in situ from Fe(ClO) and a bisquinolyldiamine ligand [(1,2)-,-di(quinolin-8-yl)cyclohexane-1,2-diamine, ]. A number of ligands (-) and the analogs of , with various substituents and chiral backbones, were synthesized and examined in the oxidative coupling reactions.
