Abstract 3-Aryl-Z-2-aroylmethylidene-1, 2-dihydroquinoxalines react with oxalyl chloride to form 3-aryl-2-(2-aryl-4, 5-dioxo-4, 5-dihydro-3-furyl) quinoxalines, whose thermal decarbonylation generate 5-aryl-2-3 (arylquinoxalin-2-yl)-4-aroyl-3-aroyloxy-1 H-pyrido [1, 2- a] quinoxalin-1-ones. The crystal and molecular structures of one of them (Ar= Ph) were established by X-ray diffraction analysis.
