摘　　要：吲哚酮类的衍生物在许多领域具有重要应用,这种特殊的杂环骨架以其独特的功能性在天然产物和生物活性分子中的应用越来越广泛.因此探索新型的吲哚酮衍生物的合成方法非常重要.报道了一种在可见光辅助下无光敏剂的磺酰化吲哚酮的高效合成方法.该方法从简单易得的N-芳基丙烯酰胺和芳基或烷基亚磺酸钠出发,使用廉价的K2S2O8作为氧化剂,具有中等至良好的产率及出色的官能团耐受性.Oxindole derivatives are well developed in many fields,and this special heterocyclic scaffold is more and more widely used in natural products and bioactive molecules due to its unique functionality.Therefore,it is very important to explore new synthesis methods for this motif.A visible light-assisted photocatalyst-free protocol for the efficient synthesis of sulfonylated oxindoles under mild condition was reported.The present method starts from simple and readily available N-arylacrylamide and sodium sulfinates,uses cheap K2S2O8as oxidant,and features moderate to good yields and excellent functional group tolerance.
