Objective: In search of new potential antimicrobial agents, the aim of the present study was synthesize the series of 1, 4-Benzothiazepine analogs by a simple and accessible approach and evaluate for their antimicrobial activity. Methods: Synthetic methodology involves the reaction of an α, β-unsaturated ketones (3 and 6) with 2-aminothiophenol and 3-4 drops of conc. HCl in methanol at 160°C, which afforded a series of novel 1,4-thiazepine derivatives (4a-f and 7a-c) in good yields. Results: The structures of the synthesized compounds were provided by spectral and elemental analysis, and by single crystal X-ray diffraction studies. The synthesised compounds were tested for their antimicrobial activity against different fungi and bacteria species in vitro. Conclusion: The results of the study reveal that the new compounds possess promising antimicrobial activities.
