Synthesis of new heterocyclic fuse compounds by reaction of N-acetyl-2-amino pyridine with  through Vilsmeier-Haack cyclization to give 2-chloro-3-formyl-1,8-naphthyridine (1) , chloro atom changing with selenium (2) or Et-S- group (3) , the formyl group in the compounds (1,2,3) converted to schiff base by react with aryl amine (4-9), shiff base derivatives  reaction with chloroacetylchloride in triethylamine to give azetidine ring (10-15) .  The structures of synthesized compounds were confirmed by spectral and physical data. Some of the newly synthesized compounds exhibited antibacterial activity.


Keywords: schiff base , 1,8-naphthyridine , azetidine , organoselenium compounds , Vilsmeier-Haack.
