quinolin-3-amines. 2-(2-Isocyanophenyl)acetonitriles and organoboron reagents are suitable substrates for this reaction. The remarkable advantages of this protocol are the practical method, mild approach, high reaction efficiency, and good compatibility of functional groups, providing straightforward access to functional quinoline derivatives.
多取代的 quinolin-3-amines 是重要的结构基序,因为它们具有广泛的生物活性和多功能的转化能力。但是,它们不容易访问。我们公开了一种使用 Mn(III) 乙酸盐作为温和的单电子氧化剂的协议,促进了构建多取代喹啉-3-胺的自由基过程。2-(2-异氰基苯基)乙腈和有机硼试剂是该反应的合适底物。该协议的显着优点是方法实用、方法温和、反应效率高、官能团兼容性好,为获得功能性喹啉衍生物提供了直接途径。
