Formal Dearomative Hydroamination of 2-Arylphenols

Abstract

An acid-promoted dearomative rearrangement of O-arylhydroxylamines affords 2-aminocyclohexadien-1-ones, which can in turn be reductively quenched for the synthesis of trans-aminoalcohols on a cyclohexadiene core. This method serves as an efficient entry to the pharmaceutically relevant 1-arylcyclohexylamine scaffold in two steps (one purification) from commercially available or readily prepared 2-arylphenols.
