Five-membered 2,3-dioxoheterocycles: LXXIII. Synthesis and thermolysis of 3-acylpyrrolo[1,2-a]quinoxaline-1,2,4(5H)-triones

Reactions of (Z)-3-(phenacylidene-2-oxo)-3,4-dihydroquinoxalin-2(1H)-ones and (Z)-3-(3,3-dimethyl-2-oxobutylidene)-3,4-dihydroquinoxalin-2(1H)-one with oxalyl chloride led to the formation of 3-acyl-1Hpyrrolo[1,2-a]quinoxaline-1,2, 4(5H)-triones that at the thermal decarbonylation generated acyl(3- oxoquinoxalin-2-yl)ketenes which underwent the intramolecular stabilization giving 3-acylfuro[3,2-b]quinoxalin-2(4H)-ones.

Five-membered 2,3-dioxo heterocycles: XLIV. Reaction of 3-aroyl-1,2,4,5-tetrahydropyrrolo[1,2-a]quinoxaline-1,2,4-triones with o-phenylenealamines

The reaction of (Z)-3-phenacylidene-1,2,3,4-tetrahydroquinoxalin-2-ones with oxalyl chloride gives 3-aroyl-1,2,4,5-tetrahydropyrrolo[1,2-a]quinoxaline-1,2,4-triones which react with o-phenylenediamine to afford 8-aryl-6,7,9,14,15,16-hexahydroquinoxalino[1
