4-Acetyl-1-alkoxyaryl-5-aryl-3-hydroxy-2,5-dihydro-1H-pyrrol-2-ones reacted with amines to give 1-alkoxyaryl-5-aryl-4-(1-R-aminoethylidene)pyrrolidine-2,3- diones. Reactions of amines with 4-benzoyl-substituted analogs involve nucleophilic attack on the C3 atom in the heteroring to produce the corresponding 3-R-amino-1-alkoxyaryl-5-aryl-4-benzoyl-2,5-dihydro-1H-pyrrol-2- ones. Reactions of the title compounds with hydrazine hydrate, regardless on the substituent on C4, afforded 4-aryl-3-methyl(phenyl)-5-[2(4)- methoxyphenyl]-4,6-dihydropyrrolo[3,4-c]pyrazol-6-ones.
