A simple and efficient method has been developed for the preparation of primary oxamates and α-ketoamides through the oxidative coupling of diazo compounds and NH4I. Under the optimized reaction conditions, a range of diazoesters and α-diazoketones was explored, and the corresponding products were obtained in moderate to good yields. This protocol is metal-free, is performed under mild conditions,
通过重氮化合物与NH4I的氧化偶合,已开发出一种简单有效的方法来制备伯草酸酯和α-酮酰胺。在优化的反应条件下,探索了一系列重氮酯和α-重氮酮,并以中等至良好的收率获得了相应的产物。该协议不含金属,可在温和条件下执行,具有广泛的基材范围,并且操作简便。
