Rhodium(III)-catalyzed three-component cascade synthesis of 6H-benzo[c]chromenes through C–H activation

Author affiliations

Abstract

A three-component cascade reaction is described that provides concise access to 6H-benzo[c]chromenes via Rh(III)-catalyzed annulation of aryl ketone O-acyloximes, quinones and acetone. Acetone acts as a co-solvent and as a reactant. This reaction shows high efficiency, atom- and step-economy, good substrate scope, excellent functional group compatibility and gives the products in good yields.
