reductant‐free approach for the efficient synthesis of various N‐acylated 2‐aminoquinolines was reported. In this work, readily available nitriles are used as the amide source, and methyl carbazate as both the radical activating reagent and oxygen source. This is the first report on the ester‐radical‐activated highly regioselective addition of nitriles to quinolone N‐oxides. This procedure is expected
报道了一种无金属,无碱和无还原剂的方法,可有效合成各种N酰化的2-氨基喹啉。在这项工作中,将现成的腈用作酰胺源,将氨基甲酸甲酯用作自由基活化剂和氧源。这是第一个关于酯基活化的高区域选择性将腈加到喹诺酮N-氧化物上的报道。预计该程序将补充当前通过亲电子激活机制对N氧化物进行功能化的方法。
