Five-Membered 2,3-Dioxo Heterocycles. XXXIX. Reaction of 4-Aroyl-1-aryl-5-methoxycarbonyl- and 1-Aryl-4-isopropyloxalo-5-phenyl-2,3-dihydropyrrole-2,3-diones with o-Phenylenediamine

4-Aroyl-1-aryl-5-methoxycarbonyl- and 1-aryl-4-isopropyloxalo-5-phenyl-2,3-dihydropyrrole-2,3-diones react with p-phenylenediamine to give substituted 1,2,3,5,10,10a-hexahydropyrrolobenzodiazepine-2,3-diones.Hydrolysis of the latter yields 3-phenacylidene-1,2,3,4-tetrahydroquinoxalin-2-ones.

Five-Membered 2,3-Dioxo Heterocycles. XLI. Reactions of 4-Acyl-2,3-dihydropyrrole-2,3-diones with o-Aminobenzenethiol

4-Acyl-2,3-dihydropyrrole-2,3-diones react with o-aminobenzenethiol to give substituted 1,2,3,10a-tetrahydro-5H-pyrrolobenzothiazepine-2,3-diones, which undergo recyclization into 1,2,3,5,10,10a-hexahydropyrrolobenzothiazepine-2,3-dione under the action of o-phenylenediamine.
