underwent this sulfonylation smoothly at room temperature under metal-free and chemical-oxidant-free conditions to afford indolyl aryl sulfones in good to high yields. This reaction was found to tolerate a variety of functional groups, including halides and cyclopropyl, ether, ester, and aldehyde groups. It was applied to the synthesis of biologically active 5-HT6 modulators.
开发了一种用芳烃亚磺酸盐电化学α-磺酰化1H-吲哚的方法。多种吲哚在室温下在无金属和无化学氧化剂的条件下顺利进行这种磺酰化,以良好或高产率得到吲哚芳基砜。发现该反应耐受多种官能团,包括卤化物和环丙基、醚、酯和醛基团。它被应用于具有生物活性的 5-HT6 调节剂的合成。
