1, 5-Benzo Thiazepine is the Main Seven membered Heterocyclic ring systems reported for their cardiac and Psychotherapeutic activities.1, 5 Benzo Thiazepines were highlighted as important Biologically active Scaffolds. In This Article New series of benzo [b] [1, 5]-thiazepine derivatives 6 a-j were synthesized by applying the cyclo condensation of (E)-3-(thieno [3, 2-d] pyrimidin-6-yl)-1-p-Substituted prop-2-en-1-one derivatives 4a-j with 2amino thio phenol (5) in DMF. The new intermediate Chalcone derivatives 4a-j were obtained from interaction of various P-substituted Acetophenone & Heterocyclic Acetyl derivatives 3(a-j) and thieno[3, 2-d]pyrimidine-7carbaldehyde. The synthesized 1, 5-benzothiazepines 6a-j have been screened for their antimicrobial activity. From anti-bacterial and anti-fungal activity screening results, it has been observed that compounds 6h, 6e, 6i and 6d possess good activity.
