Regioselective C3-Fluoroalcoholation of Indoles with Heptafluoroisopropyl Iodide via Palladium-Catalyzed C(sp<sup>2</sup>)–C(sp<sup>3</sup>) Cross-Coupling in the Presence of O<sub>2</sub>
An efficient method for C3-fluoroalcoholation of indole derivatives was developed by merging C–F cleavage and C–C bond coupling, using free (NH)-indoles and heptafluoroisopropyl iodides as precursors. Preliminary mechanistic studies indicate that the bimetallic co-mediated C–F bond cleavage and the trifluoroacetate moiety play an essential role. Notably, this strategy constructs derivatizations through

perfluoroalkyl compounds has shown huge potential in synthetic chemistry and drug development. Herein, we report a one-pot tandem perfluoroalkylation–defluorination reaction of indole, perfluoroalkyl iodide, and water in the presence of Na2S2O4. A wide array of indole derivatives were efficiently accessed with good yields under mild reaction conditions. The reaction is believed to undergo perfluoroalkylation
全氟烷基化合物的官能化在合成化学和药物开发中显示出巨大的潜力。在此,我们报道了吲哚、全氟烷基碘和水在Na 2 S 2 O 4存在下的一锅串联全氟烷基化-脱氟反应。在温和的反应条件下,可以有效地获得多种吲哚衍生物,并具有良好的收率。据信该反应经历全氟烷基化并遵循脱氟水解途径。这项研究代表了一种脱氟功能化的替代方法。
