2,3‐dihydro‐1,5‐benzothiazepinones, by an organocatalyzed sulfa‐Michael reaction of readily available α,β‐unsaturated N‐acyl pyrazoles with 2‐aminothiophenols followed by silica‐gel‐catalyzed lactamization, has been developed. The method proceeds under mild conditions at room temperature and it requires only 1 mol % catalyst loading, to give 2‐aryl/alkyl‐substituted 1,5‐benzothiazepines in generally

A practical and efficient method for the preparation of 1,5-benzothiazepinone derivatives in good yields has been developed using tetrabutylammonium fluoride (TBAF) as a catalyst. This study not only expands the previous work on the substrate scope and also provides more understanding of the chemistry of such drug scaffolds.
