Here we developed a highly efficient solvent-free, one-pot procedure for synthesizing α-ketoamides from ethylarenes and amines, by oxidizing a C–H bond sp3 center. A copper catalyst was employed, and the reactions proceeded smoothly at ambient temperatures. Most of the tested ethylarenes and amines were successfully converted to their corresponding α-ketoamides in moderate to excellent yields of up
在这里,我们开发了一种高效的无溶剂一锅法,可通过氧化C–H键的sp 3中心从乙基芳烃和胺合成α-酮酰胺。使用铜催化剂,并且反应在环境温度下顺利进行。在三当量的氧化剂叔丁基氢过氧化物的作用下,大多数被测试的乙基芳烃和胺都成功地以中等至优异的收率成功转化为它们相应的α-酮酰胺,收率高达93%。
