Abstract A visible-light induced metal-free approach was described for the hydroxyalkylation of 2H-benzothiazoles with alcohols by using selectfluor as the oxidant. A variety of 2H-benzothiazoles and alcohols could be tolerated, providing a mild and simple method for the synthesis of C2-hydroxyalkylated 2H-benzothiazoles in moderate to good yields. Besides, ethers were also compatible in this reaction
摘要描述了一种以Selectfluor为氧化剂将2H-苯并噻唑与醇进行羟烷基化的无金属诱导可见光方法。可以耐受多种2H-苯并噻唑和醇类,为中等至良好的产率合成C2-羟烷基化2H-苯并噻唑提供了一种温和而简单的方法。此外,醚在该反应中也是相容的,从而导致具有高区域选择性的相应的C 2醚取代的2H-苯并噻唑。
