Abstract

A palladium-catalyzed synthesis of 3-arylquinolin-2(1H)-ones proceeds through a reductive aminocarbonylation of benzylic ammonium triflates with o-nitrobenzaldehydes. The reaction provides a wide range of 3-arylquinolin-2(1H)-ones in good yields with very good functional group compatibility.
