  摘要：

  使用频哪醇硼烷对丰富的乙烯基三氟甲磺酸酯和未活化的芳基羧酸酯进行硼酸化是通过铬催化选择性形成乙烯基和芳基硼酸酯实现的。竞争性氢化还原或烯丙基硼化反应缓慢或不发生，因此为将硼酸盐结合到烯烃和芳烃中提供了一种选择性策略。机理研究表明，σ键复分解或氧化加成机制可能被认为是酯支架断裂的原因。

• Interrupted Fischer-Indole Intermediates via Oxyarylation of Alkenyl Boronic Acids
  作者：Heng-Yen Wang、Laura L. Anderson

  DOI：10.1021/ol401416r

  日期：2013.7.5

  The oxyarylation of alkenyl boronic acids with N-arylbenzhydroxamic acids has been achieved under both copper-mediated and copper-catalyzed conditions to provide access to interrupted Fischer-indole intermediates. This transformation is believed to proceed through a copper-promoted C–O bond forming event followed by a [3,3] rearrangement. The scope of the method is described and mechanistic experiments

  Herein we describe an iron-catalyzed borylation of alkenyl and aryl carbamates through the activation of a C–O bond. This protocol exhibits high efficiency, a broad substrate scope, and the late-stage borylation of biorelevant compounds, thus providing potential applications in medicinal chemistry. Moreover, this method enables orthogonal transformations of phenol derivatives and also offers good opportunities

  在本文中，我们描述了通过C-O键的活化，铁催化的烯基和芳基氨基甲酸酯的硼酸酯化反应。该方案显示出高效率，广泛的底物范围以及生物相关化合物的后期硼化，因此在药物化学中提供了潜在的应用。而且，该方法能够使酚衍生物进行正交转化，并且还为合成多取代的芳烃提供了良好的机会。初步的机理研究表明，通过自由基途径的Fe II / Fe III催化循环可能与反应有关。
