Abstract: The first general protocol for the synthesis of 1,3-benzothiazepine derivatives was established. With the aid of bench-stable hypervalent iodine promoter fluoro-HTIB, these seven-membered heterocycles can be rapidly synthesized from readily available thioamides under air atmosphere… read more here.
