摘要
Four title compounds were synthesized, their spectral properties including IR,MS, 1H NMR and their steric structures were studied. The conformation of the seven-mem-bered ring is chair-like and the two phenyl substituents on the β-lactam ring adopt cis configuration. It is proposed that the reaction of 1,5-benzothiazepines with acyl chloride is a stereospecific one.
