  • Metal-free regioselective C–H amination for the synthesis of pyrazole-containing 2<i>H</i>-indazoles
    作者:Kai Wang、Tingting Wei、Yujia Zhang、Jiahao Hou、Renren Bai、Yuanyuan Xie
    DOI:10.1039/d0ob02485f
    日期:——
    A general and practical regioselective approach for the C–H amination of 2H-indazoles under transition-metal-free conditions was developed. A series of substrates were tested showing eminent functional group tolerance and affording the C–N functionalization products in good to excellent yields. Mechanism studies revealed that a radical process was involved in this transformation.

    direct synthesis of 3-substituted-2H-indazole derivatives was developed in the presence of AgNO3/Na2S2O8 under mild reaction conditions. The reaction affords a series of 1,3-dicarbonyl-2H-indazoles products with yields of up to 82%. The mechanism of the strategy suggests that the reaction proceeds through a radical pathway. Moreover, this strategy provides a new protocol for the synthesis of functionalized

  • A Facile One-Step Synthesis of 2-Arylindazoles via Reductive Cyclization of<i>N</i>-(2-nitroarylidene)amines
    作者:Wei Lin、Minghua Hu、Xian Feng、Chengpao Cao、Zhibin Huang、Daqing Shi
    DOI:10.1002/jhet.2221
    日期:2015.7
    A mild and efficient synthesis of 2‐arylindazole derivatives via the reductive cyclization of nitro‐aryl substrates mediated by a low‐valent titanium reagent (TiCl4/Sm/Et3N) has been developed. The attractive features of the current method include an N–N bond formation and the selective reduction of the C = N bond and nitro group, both of which were easily achieved in one‐pot by controlling the pH
    通过低价试剂(TiCl 4 / Sm / Et 3 N)介导的硝基芳基底物的还原环化,可以温和有效地合成2-芳基吲唑生物。当前方法的吸引人的特征包括N–N键的形成以及C = N键和硝基的选择性还原,通过控制反应混合物的pH值,很容易在一个锅中完成这两个操作。
