intramolecular C–N bond formation of 2-nitrile-2′-alkenyl(alkynyl)biphenyls with amines has been developed, which provides a straightforward and efficient access to a range of new functional dibenzo[c,e]azepines. This represents the first examples of direct construction of seven-membered azaheterocycle from unsaturated nitriles and amines. Such transformations have the advantages of avoiding the use of additives
已经开发了一种稀土
金属催化的 2-腈-2'-烯基(炔基)
联苯与胺的分子间和分子内连续 C-N 键形成,这为获得一系列新的功能性二苯并提供了一种直接有效的途径。c , e ]氮杂。这代表了从不饱和腈和胺直接构建七元氮杂杂环的第一个例子。这种转化具有避免使用添加剂、原料易得、分步经济和高原子经济性、反应条件温和、选择性高的优点。
