from 2-bromobenzamides and 2-bromo(thio)phenols via twice copper-catalyzed couplings to afford dibenzothiazepines and dibenzoxazepinones has been developed. High levels of yield and chemoselectivity are achieved in a single-pot reaction by using an appropriate ligand. Moreover, this facile methodology allows rapid access to a variety of bioactive compounds and known psychotropic drug, which should
已经开发了一种高效且普遍适用的协议,从 2-溴苯甲酰胺和 2-溴(硫)酚开始,通过两次铜催化偶联,提供二苯并噻嗪类和二苯并恶唑酮。通过使用合适的配体,在单锅反应中实现了高水平的产量和化学选择性。此外,这种简便的方法可以快速获得各种生物活性化合物和已知的精神药物,这将扩大其在有机合成中的应用。
