Five-membered 2,3-dioxo heterocycles: L. Synthesis and thermolysis of 3-aroyl- and 3-hetaroyl-5-phenyl-1,2,4,5-tetrahydropyrrolo[1,2-a]quinoxalin-1,2, 4-triones

(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

1-Aryl-4-aroyl-5-methoxycarbonyl-2,3-dihydro-2,3-pyrrolediones react with o-aminophenol and N-phenyl-o-phenylenediamine with the formation of 1-aryl-4-aroyl-5-methoxycarbonyl-3-hydroxy-5-o-hydroxyphenylamino- and 5-o-phenylaminophenylamino-2,5-dihydro-2-p
