meta‐substituted phenols in which a single palladium catalyst accomplishes a Suzuki–Miyaura cross‐coupling between a β‐chlorocyclohexenone and an arylboronic acid, and oxidation of the resulting cyclohexenone to the corresponding phenol upon introduction of a terminal oxidant and electron transfer mediator. Notably, this method also allows ready access to ortho, meta‐disubstituted phenols, sterically congested

Substitutedphenols are requisite molecules for human health, agriculture, and diverse synthetic materials. We report a chemical synthesis of phenols, including penta-substituted phenols, that accommodates programmable substitution at any position. This method uses a one-step conversion of readily available hydroxypyrone and nitroalkene starting materials to give phenols with complete regiochemical
