| Abstract: | Depending on the reaction condition, 1-(4-aminosulfonylphenyl)-5-aryl-4-aroyl-3-hydroxy-3-pyrrolin-2-ones reacted with aromatic amines to yield 3-arylamino-3-pyrrolin-2-ones or 4-[aryl (arylamino) methylene]tetrahydropyrrole-2,3-diones. Reactions of 1-(4-aminosulfonylphenyl)-5-aryl-4-aroyl-3-hydroxy-3-pyrrolin-2-ones with hydrazine hydrate afforded pyrrolo[3,4-c]pyrazol-6-ones. |
