Synthesis and Biochemical Investigation of (Thiazin, Oxadiazol, Thiadiazol )- Derivatives .

Abstract

The study involved synthesis of six and five- membered rings from hetero cyclic compounds containing sulfur and nitrogen with  oxygen atoms such as (thiazine, oxadiazol, thiadiazol)- derivatives., some of compounds were prepared from condensation reaction and other by chalcone .The synthesized compounds [1-10] were characterized by many methods {FT.IR- spectra, H.NMR- spectra, (C.H.N)- analysis} and tested for their potential antibacterial {Gram(+) positive and Gram(-) negative} and melting points .

Keywords: thiazine, chemical, oxygen .
