摘要

介绍了一种高效的有机碘催化分子内直接 C-N 键氧化偶联反应。在一个复杂的氧化体系中迅速获得了结构多样的 3-（单）取代吲哚，收率高达 87%。各种 N-烷氧基-2-苯基丙酰胺的耐受性良好。这项研究表明，反应物芳香环上的电子效应对环化产物的选择性（C-N/C-O）有至关重要的影响。此外，3-（单）取代吲哚衍生物的克级合成和后期修饰揭示了这种转化的实际应用。

Organoiodine Catalysed Intramolecular C−N bond Oxidative Coupling for the Synthesis of 3-Monosubstituted Oxindoles

An efficient organoiodine-catalysed intramolecular direct C–N bond oxidative coupling reaction is presented. Structurally diverse 3-(mono)substituted oxindoles were rapidly obtained in a complex oxidative system in up to 87% yield. Various N-alkoxy-2-phenylpropanamides were well-tolerated. This study showed that the electronic effects on the aromatic ring of reactants have a crucial effect on the selectivity (C−N/C−O) of cyclisation products. In addition, gram-scale synthesis and late-stage modification of 3-(mono)substituted oxindole derivatives revealed the practical application of this transformation.
