Abstract

BENZENE-1,4-dicarbaldehyde (1) reacted with 2-cyanoethane- …. thioamide (2) to give 3,3'-benzene-1,4-diylbis(2-cyanoprop-2-enethioamide) (3) which in turn, reacted with pentane-2,4-dione (4) to afford the corresponding 4,4'-benzene-1,4-diylbis(5-acetyl-6-methyl-2-thioxo-1,2-dihydropyridine-3-carbonitrile)(5). The synthetic potentiality of compound 5 was investigated in the present study via its reaction with several reagents to afford newly synthesized 4,4'-(1,4-phenylene)-bis (5-acetyl-3-amino-6-methylthieno [2,3-b] pyridines (8a-h). Structures of all newly synthesized heterocyclic compounds in the present study were confirmed by considering the data of IR, 1H NMR, mass spectra as well as that of elemental analyses
