(Z)-3-Phenacylidene- and (Z)-3-hetaroylmethylidene-1-phenyl-1,2,3,4- tetrahydroquinoxalin-2-ones react with oxalyl chloride to give 3-acyl-5-phenyl-1,2,4,5-tetrahydropyrrolo[1,2-a]quinoxaline-1,2,4-triones. Thermolysis of the latter generates acyl(3-oxo-4
FIVE-MEMBERED 2,3-DIOXOHETEROCYCLES XXXI. REACTION OF 1-ARYL-4-AROYL-5-METHOXYCARBONYL-2,3-DIHYDRO-2,3-PYRROLEDIONES WITH o-AMINOPHENOL AND N-PHENYL-o-PHENYLENEDIAMINE
