A simple, environmentally benign, and efficient method was developed for the preparation of 1,5-benzothiazepines via a one-pot condensation reaction of 2-aminothiophenol with 1,3-diaryl-2-propenones using tetrabutylammonium tribromide as an efficient and versatile catalyst in water.
Syntheses of potentially bioactive [1,2,4]oxadiazolo[5,4-d]benzothiazepines by 1,3-dipolar cycloaddition

experimental part, p. 1350 - 1355 (2011/01/05)
The chalcones, 2a-2l reacted with o-aminobenzenthiol to give a series of 1,5-benzothiazepines, 3a-3l. The [3+2] 1, 3-dipolar cycloaddition reactions of 3a-3l with ethyl chlorooximidoacetate in the presence of Et3N afforded the target compounds, 4a-4l possessing an additional 1,2,4-oxadiazole ring fused to the heptaatomic nucleus. The structures have been elucidated by spectral methods and X-ray crystallographic analysis.
Fluoroboric acid adsorbed on silica-gel (HBF4-SiO2) as a new, highly efficient and reusable heterogeneous catalyst for thia-Michael addition to α,β-unsaturated carbonyl compounds
