Abstrakt: 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. [ABSTRACT FROM AUTHOR]
