We developed a redox-neutral synthesis of isoindoloindolone via intramolecular arylation of 2-(1H-indole-1-carbonyl)benzoic acids. This protocol facilitates the formation of various substituted isoindoloindolones in yields ranging from 17% to 80%. Our mechanistic investigations indicate the pivotal role of NaI: the iodide anion promotes the formation of the desired isoindoloindolone, and the sodium
我们通过 2-(1 H-吲哚-1-羰基)苯甲酸的分子内芳基化开发了异吲哚并吲哚酮的氧化还原中性合成。该方案促进了各种取代异吲哚并吲哚酮的形成,产率范围为 17% 至 80%。我们的机理研究表明 NaI 的关键作用:碘化物阴离子促进所需异吲哚并吲哚酮的形成,钠阳离子抑制酰化副产物的形成,从而能够以可接受的产率选择性形成异吲哚并吲哚酮。
