“…Heterocyclic molecules are of great interest due to their many applications [1][2][3][4] especially in medicinal chemistry. 5,6 The synthesis of compounds belonging to the thiazepine and diazepine series is an important area of research due to their diverse biological activities, such as antibacterial, 7 antifeedent, 8 analgesic, 9 anticoagulant, 10 antihypertensive, 11 and antidepresent 12 properties. In addition, 1,5-benzothiazepines and benzodiazepines are used as starting materials for the preparation of fused ring compounds, such as triazolo-, 13,14 oxazino-, 14 or furano-benzodiazepine.…”
