Copper‐Catalyzed C(sp2)−N Coupling of (E)‐3‐(2‐Bromophenysl)‐2‐arylacrylamides for the Synthesis of 3‐Arylquinolin‐2‐ones

Abstract A copper‐catalyzed, facile and efficient approach for the synthesis of 3‐arylquinolin‐2‐ones starting from (E) ‐3‐(2‐bromophenyl)‐2‐arylacrylamides has been developed. Readily available starting materials, noble metal‐ and ligand‐free conditions, as well as good tolerability for phenolic groups make this protocol attractive and practicable.
