Eight α-maleimido substituted-β-lactam derivatives of 1,5-benzothiazepines were synthesized and their structures were confirmed by elemental analysis, IR, MS and 1H NMR specta. The configuration and conformation of the products were determined by single crystal X-ray diffraction. The primary biological activity assay showed that most of the products had weak to medium antibacterial activities against S. Aureus, S. Albus, E. Coli, and B. Albicans.

Key words: β-lactam, 1,5-benzothiazepine, crystal structure, antibacterial activity
