Application of Chalcones in Synthesis of Novel 1, 5-Benzodiazepine Derivatives Containing Thieno [2,3-d] Pyrimidine Core Unit and its Biological Activity Screening

摘要

Di azepines, which were synthesized by different methods shown in literature and also Di azepines are great importance in heterocyclic chemistry and more importance in biology and pharmacology. Di azepines are very biological active molecules. In this work A new series of 1,5-Benzodizepine derivatives were synthesized from chalcones and evaluated for their Antimicrobial activities. First Chalcones were prepared by treatment of Thieno [2, 3-d] pyrimidine-6-carbaldehyde with different acetophenones by Claisen-Schimidt Condensation. Various Benzodiazepines derivatives were prepared by reaction of Chalcone in DMF with o-phenylene di amine in presence of piperidine. The structures of the newly synthesized Benzodiazepine derivatives have been established on the basis of their spectral data. The synthesized selected compounds were evaluated for their antimicrobial activities.
