and green synthetic strategies for N-heterocycle synthesis has always been a research hotspot in organic synthesis. A facile one-pot iron-catalyzed synthesis of quinazolinesfrom alcohols in water has been disclosed for the first time, in which a N-doped carbon encapsulated Fe–FeOx material (Fe–FeOx@NC) is applied as a catalyst, and various quinazolines (25 examples, 62–99%) are synthesized. The iron
开发高效、绿色的N-杂环合成策略一直是有机合成领域的研究热点。首次公开了一种简便的铁催化水中醇合成喹唑啉的方法,其中将 N 掺杂碳包覆的 Fe-FeO x材料(Fe-FeO x @NC)用作催化剂,并合成了各种喹唑啉(25 个实例,62-99%)。Fe-FeO x @NC中被氮掺杂碳层包裹的铁纳米颗粒具有很强的抗毒能力,是该反应具有高性能的主要原因。该协议提供了几个优点,包括使用空气作为氧化剂、水作为溶剂、可回收铁作为催化剂以及高原子和步骤经济性。
