An efficient method for the C(sp2) amidation of 8-aminoquinoline benzamide by acyl azide in the presence of copper acetate has been achieved via C–H activation. Interestingly, the loading of copper acetate has a strong influence on the outcome of the reaction. The use of 1 equiv of copper acetate produces the corresponding aroyl amide, whereas the use of 2 equiv led to acetyl amide. A series of substituted
在乙酸铜存在下,通过酰基叠氮化物对8-氨基喹啉苯甲酰胺进行C(sp 2)酰胺化的一种有效方法是通过C–H活化实现的。有趣的是,乙酸铜的负载量对反应的结果有很大的影响。使用1当量的乙酸铜产生相应的芳酰基酰胺,而使用2当量的乙酸酯产生乙酰基酰胺。已经获得了一系列取代的苯甲酰基和乙酰基酰胺。
