title: Synthesis of some 3- and 4-substituted 1,5-diphenylpyrrolidine-2,4-diones as potential antimicrobial and antineoplastic agents. Reactions with tetramic acid, Part 5.
abstract: The condensation of 1,5-diphenylpyrrolidine-2,4-dione (1) with the carboxyl compounds 2a-f afforded the corresponding 3-arylidene-1,5-diphenylpyrrolidine-2,4-diones 3a-f. Reaction of the parent compound 1 with isatin (4) yielded the condensation product 5 in an acidic medium, whereas compound 6 was obtained in an alkaline medium. The condensation of the primary amines 7a-f with compound 1 afforded the corresponding 4-substituted amino-1,5-diphenyl-delta 3-pyrrolin-2-ones 8a-f. All the compounds synthesized were screened for their antimicrobial activity, and four compounds were selected for screening for their antineoplastic activity. The compounds tested showed both antimicrobial and antineoplastic activities.
