of 2-(1-(naphthalen-2-yl) ethylidene) hydrazine-1-carbothioamide [I] with ethyl α-chloroacetate in the presence of fused CH3COONa. The new 2-thioxo-imidazlidin-4-one derivatives containing heterocyclic unit, five, and seven-member ring\ were successfully formed, such as imidazoline-4-one, tetrazole, thiazolidin-4-one, and 1,3-oxazepinerings. The synthesized derivatives were characterized by their FTIR,1H-NMR, mass spectra, and CHN-S. Furthermore, the synthesized compounds have been screened for their antibacterial activity against E.col (G-), Staph. Aureus (G+), and Bacillus cereus(G+), and compared to Ampicillin, Amoxicillin, and Lincomycin as antibiotic standards.
