Diversification of Naphthol Skeletons Triggered by Aminative Dearomatization

A silver-catalyzed aminative dearomatization of naphthols has been developed and integrated into a stepwise approach for subsequent skeletal diversifications including ring expansion, ring opening, ring contraction, and atom transmutation of aryl scaffolds. This approach enables the synthesis of a diverse array of azepinones, unsaturated amides, isoquinolines, and indenones from naphthol substrates. Its application in the synthesis of bioactive and functional molecules as well as the conversion of complex molecular skeletons underscores its broad potential applicability. Mechanistic investigations suggest the intermediacy of the dearomatized intermediates.
