Copper-Catalyzed One-Pot Synthesis of Substituted Benzimidazo[1,2-a]quinolines

[摘要]：A one-pot procedure for the synthesis of substituted benzimidazo[1,2-a]quinolines from the corresponding benzimidazoles and 2-bromobenzaldehydes has been developed. The titled products were prepared through Knoevenagel condensation and copper-catalyzed intramolecular Ullmann-type coupling in moderate to good yields.
