A new and efficient method for the synthesis of 2-phenyl-4-quinolones and 2-phenyl-2,3-dihydroquinolin-4(1H)-ones is described. The reaction involves ZnCl2-mediated polystyrene-supported selenium-induced intramolecular cyclization of 2-aminochalcones and subsequent traceless or functionalizing cleavage of selenium linker.
