Enantioselective Addition of Boronates to Ortho-Quinone Methides Catalyzed by Chiral Biphenols
Chiral biphenols were found to catalyze the enantioselective asymmetric addition of aryl- or alkenyl-boronates to ortho-quinone methides. Substituted 2-styryl phenols were obtained in good yields (up to 95%) and high enantiomeric ratios (up to 98:2) in presence of 10 mol % of 3,3′-Br(2)-BINOL. A two...
