Selective preparation of optically pure (R,R)-1,1':5',1''- ternaphthalene-2,2',6',2''-tetraol: A new higher homolog of BINOL

Article abstract of DOI:10.1016/S0040-4039(98)01381-1

As a new chiral auxiliary, the title compound of an enantiomerically pure higher homolog of BINOL was synthesized through stepwise formation of optically pure 2,4-pentanediol tethers connecting three naphthyl groups by Mitsunobu reaction, oxidative intramolecular coupling, and elimination of the tethers.
