A new, efficient, metal-free, and DMSO-assisted approach for the synthesis of N-alkylated quinazolinones from readily available 2-aminobenzamide and aryl methyl ketones in the presence of an oxidizing agent has been developed. In this unique tandem reaction, DMSO played a dual role, acting as a solvent as well as a dual carbon synthon, making this process an environmentally benign approach to accessing
已经开发了一种新的、有效的、无金属的和 DMSO 辅助的方法,用于在氧化剂存在下从容易获得的 2-氨基苯甲酰胺和芳基甲基酮合成N-烷基化喹唑啉酮。在这种独特的串联反应中,DMSO 发挥了双重作用,既作为溶剂又作为双碳合成子,使该过程成为一种环境友好的方法来获得药用流行的N-烷基化喹唑啉酮。DMSO 辅助分别从 2-氨基苯甲酰胺和芳基甲基酮原位生成亚胺阳离子和 α,β-不饱和酮是该方法的关键特征。
