variety of substituted 6H-isoindolo [2, 1-a] indoles were prepared by a simple and efficient intramolecular cyclization using 1,10-phenanthroline in the presence of potassium tert-butoxide and chlorobenzene. This strategy provides a fast and versatile access to isoindolo[2,1-a]indole derivatives for the synthesis of pharmaceuticals and organic electroluminescent (EL) materials.
已经开发出第一个实例,菲咯啉t BuOK促进了N-(2-碘苄基)吲哚的分子内自由基C–H芳基化,而没有过渡金属的参与。在叔丁醇钾和氯苯存在下,使用1,10-菲咯啉通过简单有效的分子内环化反应制备了多种取代的6 H-异吲哚并[2,1-a]吲哚。该策略为异吲哚并[2,1- a ]吲哚衍生物的合成提供了快速而通用的途径,用于合成药物和有机电致发光(EL)材料。
