Chiral phosphoric acid catalyzed asymmetric addition of naphthols to para-quinone methides.

Yuk Fai Wong1, Zhaobin Wang, Jianwei Sun.   

Abstract

An asymmetric addition of naphthols to in situ generated para-quinone methides catalyzed by a chiral phosphoric acid is described. A range of useful triarylmethanes can be generated from stable general para-hydroxybenzyl alcohols with good efficiency and enantioselectivity.
