The title reaction proceeds through an oxidation/cyclization sequence, thus representing the first copper‐catalyzed coupling reaction of hydrazones through a CH bond functionalization process (see scheme; DMF=N,N′‐dimethylformamide, Py=pyridine). The method provides an environmentally friendly and atom‐efficient approach to biologically active cinnoline derivatives.
O 2 占主导地位:标题反应按氧化/环化顺序进行,因此代表through通过CH键官能化过程进行的首次铜copper偶联反应(请参阅示意图; DMF = N,N'-二甲基甲酰胺,Py =吡啶)。该方法为生物活性的cinnoline衍生物提供了一种环境友好且原子效率高的方法。
