novel and efficient method for the synthesis of α-ketoamides, employing a dimethyl sulfoxide (DMSO)-promoted oxidative amidation reaction between 2-oxoaldehydes and amines under metal-free conditions is presented. Furthermore, mechanistic studies supported an iminium ion-based intermediate as a central feature of reaction wherein C1-oxygen atom of α-ketoamides is finally derived from DMSO.
提出了一种新颖而有效的合成α-酮酰胺的方法,该方法利用二甲基亚砜(DMSO)促进了2-氧代醛和胺在无金属条件下的氧化酰胺化反应。此外,机理研究支持基于亚胺离子的中间体作为反应的主要特征,其中α-酮酰胺的C 1-氧原子最终衍生自DMSO。
