Abstract

This article presents a synthetic method and reaction mechanism of the 1,5-benzothiazepines and 1,5-benzodiazepines derivatives. In this research, 36 thiazepines and diazepines (mostly new) with a new method have been prepared and their structures have been characterized by spectroscopic methods. Crystal structures of a new thiazepine and diazepine (seven-membered rings) have also been determined and compared with thiazine (six-membered ring). In this method, N-methylimidazolium nitrate [Hmim][NO3] has been used as a catalyst that acts as an environmental friendly system.
