N-Aryl amides are an important class of compounds in pharmaceutical and agrochemical chemistry. Rapid and low-cost synthesis of N-aryl amides remains in high demand. Herein, we disclose an operationally simple process to access N-aryl amides directly from readily available nitroarenes and carboxylic acids as coupling substrates. This method involves the in situ activation of carboxylic acids to acyloxyphosphonium
N-芳基酰胺是药物和农业化学中重要的一类化合物。对N-芳基酰胺的快速且低成本的合成仍然有很高的需求。本文中,我们公开了一种操作简单的方法,可直接从容易获得的硝基芳烃和羧酸作为偶联底物直接获得N-芳基酰胺。该方法涉及将羧酸原位活化为酰氧基phosph盐以进行一锅酰胺化,而无需分离相应的合成中间体。此外,制备和后处理的简便性允许快速有效地合成多种N-芳基酰胺,包括几种基于酰胺的类药物和农用化学分子。
