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.
