当前用于构建酰胺键的方法通过脱水偶联过程将胺和羧酸连接起来,该过程通常需要有机溶剂、昂贵且通常危险的偶联试剂,并掩盖其他官能团。在这里,我们描述了使用伯胺和酰基三氟硼酸钾的酰胺形成,由在水中快速进行的简单氯化剂促进。该反应在酸性 pH 值下很快,并且可以耐受底物中的醇、羧酸,甚至仲胺。它适用于伯酰胺、磺酰胺和其他通常抵抗经典酰化的 N 官能团的官能化,并可应用于后期官能化。
A novel and efficient palladium-catalyzed aminocarbonylation of aryliodides with amides and N-alkyl anilines has been developed. The reaction tolerates a wide range of functional groups and is a reliable method for the rapid synthesis of a variety of valuable imides and tertiary benzanilides under an atmospheric pressure of CO.
