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 2-amino 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-7-carbaldehyde. 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.
