  • Title: Reversal of Enantioselectivity Approach to BINOLs via Single and Dual 2-Naphthol Activation Modes.
    Author: Kim HY, Takizawa S, Sasai H, Oh K.
    Journal: Org Lett; 2017 Jul 21; 19(14):3867-3870. PubMed ID: 28696128.
    Abstract:
    A mechanism-driven enantiodivergent approach to chiral 1,1'-bi-2-naphthols via catalytic asymmetric oxidative coupling of 2-naphthol derivatives is described for the first time. By utilizing 2-naphthol derivatives with low oxidation potential, the substrates were activated by either chiral mononuclear or dinuclear vanadium(V) catalyst to promote distinctively different asymmetric reaction pathways: single versus dual substrate activation mechanisms.
