  摘要：

  提出了一种新的一锅式硝化方法，该方法采用硝酸四甲基铵和三氟甲磺酸酐在二氯甲烷中的溶液，以提供易于使用的三氟甲磺酸硝化硝化剂的来源。实现了多种芳香族和杂芳香族底物的快速选择性硝化，从而合成了几种新型有机化合物。一个明显的优点是通过水后处理除去不需要的副产物。这种非常温和的硝化作用可实现大规模合成，并获得较高的分离产物收率，而通常无需进一步纯化。这种基于硝酸四甲基铵的硝化也已应用于微波辅助条件，并概述了几种化合物的结果。

  We previously reported a facile preparation method of 3-substituted-2,6-difluoropyridines, which were easily converted to 2,3,6-trisubstituted pyridines by nucleophilic aromatic substitution with good regioselectivity and yield. In this study, we demonstrate the synthetic utility of 3-substituted-2,6-difluoropyridines in drug discovery via their application in the synthesis of various 2,3,6-trisubstituted
