Ten azeto[2,1-d][1,5]benzothiazepinone derivatives 6a–j were synthesized starting from 4-acetyl-2-phenyl-1,2,3-triazole 1. First, condensation of 1 with various aldehydes 2a–e afforded α,β-unsaturated carbonyl compounds 3a–e, which subsequently underwent cyclization with o-aminothiophenol to yield the corresponding 2,4-disubstituted-1,5-benzothiazepines 4a–e. Treatment of 4a–e with chloroacetyl chloride
