Electrochemical Dearomative Amination of Phenol Derivatives: Access to Spirooxazolidinones

Abstract

AbstractAn electrochemical oxidative approach to spirooxazolidinones from phenol derivatives via intramolecular dearomative amination reactions is developed. This reaction proceeds without metal catalysts and external chemical oxidants, and shows broad substrate scope and diverse functional group compatibility. The synthetic utility of this strategy is further exhibited by the gram‐scale synthesis and late‐stage functionalization. By slightly tunning the reaction conditions, the alcohols (1°, 2° and 3°) can be afforded from phenol derivatives, which is a good strategy for the deprotection of para‐methoxyphenyl (PMP) group to recover the alcohol function.magnified image
