experimental part, p. 707 - 711 (2011/04/26)
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-amino-chalcones and subsequent traceless or functionalizing cleavage of selenium linker.

A panel of 1-benzyl-2-aryl-4-quinolones was synthesized in three steps and converted to the corresponding 4-thione derivatives using Lawesson's reagent. The representative vinylogous thioamide (5a) was alkylated to afford a novel series of quinolinium sal
