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 triethylamine in anhydrous benzene. The stereochemistry was discussed for the cycloaddition reaction. © 2002 Wiley Periodicals
