The mass spectrometric behaviour of seven tetrasubstituted 3a ,4,5,2,3d][1,5]benzothiazepines has been studied with the aid of mass-analysed ion kinetic energy spectrometry and exact mass measurements under electron impact ionization. All compounds show a tendency to eliminate a neutral substituted
## Abstract 2a,4‐Disubstituted 2‐phthalimido‐2a,3,4,5‐tetrahydro‐1H‐azeto[2,1‐d][1,5]benzothiazepin‐1‐ones were synthesized by cycloaddition reactions of 2,4‐disubstituted 2,3‐dihydro‐1,5‐benzothiazepines and phthalimidoketene, generated from phthalimidoacetyl chloride, in the presence of triethyla
