  of arenes bearing ortho/para directing group(s) using the iridium‐catalyzed C−H borylation reaction followed by a newly developed copper(II)‐catalyzed transformation of the crude aryl pinacol boronate esters into the corresponding nitroarenes in a one‐pot fashion. This protocol allows the synthesis of meta‐nitrated arenes that are tedious to prepare or require multistep synthesis using the existing

  在本文中，我们报道了荟萃芳烃的-nitration轴承邻/对位用铱催化的C-H硼化反应之后是新开发的铜（II）粗频哪醇的芳基硼酸酯入的催化的变换引导组（多个）以一锅的方式对应的硝基芳烃。该协议允许的合成元-nitrated芳烃是乏味来制备或使用现有的方法需要多步合成。该反应可耐受多种邻位/对位导向基团，例如-F，-Cl，-Br，-CH 3，-Et，-i Pr -OCH 3和-OCF 3。它还提供对π电子缺陷杂环的硝基衍生物（例如吡啶和喹啉衍生物）的区域选择性访问。该方法的应用在复杂分子的后期修饰中以及在以克级制备到FDA批准的药物Nilotinib途中的中间体中得到了证明。最后，我们证明了通过该策略获得的硝基产物也可以通过Baran的胺化方案直接转化为苯胺或受阻胺。
