I2-TBHP-catalyzed azomethine imine generation and subsequent regioselective 1,3-dipolar cycloaddition (DC) with aromatic N-heterocycles was developed to afford various 4,3-fused 1,2,4-triazoles in excellent yields. The method is operationally simple and highly efficient with broad functional group tolerance.
开发了I 2 -TBHP催化的偶氮甲亚胺亚胺和随后的具有芳香族N-杂环的区域选择性1,3-偶极环加成(DC),以优异的产率提供了各种4,3-稠合的1,2,4-三唑。该方法操作简便且高效,具有宽泛的官能团耐受性。
