dearomatization of 2‐substituted phenols to either 1,2‐benzoquinols or their cyclodimers, catalyzed by 4,5‐dimethyl‐2‐iodoxybenzenesulfonic acid with Oxone, has been developed. Natural products such as biscarvacrol and lacinilene C methyl ether could be synthesized efficiently under mild reaction conditions. Furthermore, both the reaction rate and site selectivity could be further improved by the introduction of
