Synthesis of Functionalized 4,1‐Benzothiazepines via a [4+3] Annulation between Aza‐o‐Quinone Methides and Pyridinium 1,4‐Zwitterionic Thiolates

“…Benzothiazepines can be divided into several types according to the structure, i. e . 1,2‐ 1,3‐, 1,4‐, 1,5‐, 2,1‐ and 4,1‐benzothiazepines (Figure 1) [2] and all of them often show a wide range of biological activities. For example, 1,4‐benzothiazepine derivative Ziresovir is a potent, selective and orally bioavailable inhibitor of respiratory syncytial virus fusion (RSV F) protein [3] .…”
