Synthesis and biological evaluation of 5-chalcogenyl-benzo[h]quinolines via photocyclization of arylethynylpyridine derivatives

A new and efficient method for the synthesis of 6-organyl-5-(arylselanyl)benzo[h]quinolines via visible light-promoted intramolecular ortho-cyclization of 2-aryl-3-(organylethynyl)pyridines has been achieved. The reaction was promoted by radical organochalcogen species generated in...
