Herein, we report a two-step process forming arene C-O bonds in excellent site-selectivity at a late-stage. The C-O bond formation is achieved by selective introduction of a thianthrenium group, which is then converted into C-O bonds using photoredox chemistry. Electron-rich, -poor and -neutral arenes as well as complex drug-like small molecules are successfully transformed into both phenols and various
在此,我们报告了一种在后期以优异的位点选择性形成芳烃CO键的两步过程。CO 键的形成是通过选择性引入铊基团来实现的,然后使用光氧化还原化学将其转化为 CO 键。富电子、贫电子和中性芳烃以及复杂的类药物小分子被成功转化为酚类和各种醚类。该序列在概念上不同于所有先前的芳烃氧化反应,因为氧官能团可以在后期选择性地结合到复杂的小分子中,这尚未通过芳基卤化物显示出来。
