• Iridium-Catalyzed <i>ortho</i>-C(sp²)–H Amidation of Benzaldehydes with Organic Azides
  作者：Delong Mu、Xinmou Wang、Gong Chen、Gang He

  DOI：10.1021/acs.joc.7b00531

  日期：2017.4.21

  ortho-C(sp2)–H amidation reaction of benzaldehydes with organic azides has been developed. A catalytic amount of 3,5-di(trifluoromethyl)aniline was used to promote the Ir-catalyzed directed C–H amination reaction through a transient aldimine intermediate. This reaction tolerates a broad scope of benzaldehyde substrates and works well with a range of aryl- and alkylsulfonyl azides.

  已开发出铱催化的苯甲醛与有机叠氮化物的邻位C（sp 2）-H酰胺化反应。催化量的3,5-二（三氟甲基）苯胺用于通过短暂的亚胺中间体促进Ir催化的直接CH胺化反应。该反应可耐受各种范围的苯甲醛底物，并能与多种芳基和烷基磺酰基叠氮化物一起很好地起作用。

  oxygen-centered nucleophile. We show the desired reactivity in the reduction of benzylic alcohols to the corresponding benzyl radicals with terminal H atom trapping to afford the deoxygenated products. Using the same method, we demonstrate access to synthetically versatile acyl radicals, which enables the reduction of aromatic and aliphatic carboxylic acids to the corresponding aldehydes with exceptional chemoselectivity

  尽管醇和羧酸作为有机分子中的官能团盛行，并且有可能用作自由基前体，但C-O键仍然难以激活。我们报告了通过光氧化还原催化直接从这些普遍存在的官能团同时进入烷基和酰基自由基的合成策略。该方法利用了磷化氢自由基的独特反应性，该反应是由膦自由基阳离子和以氧为中心的亲核试剂之间的极性/ SET交叉产生的。我们显示了在末端醇被俘获以提供脱氧产物的情况下，将苄醇还原为相应的苄基所需要的反应性。使用相同的方法，我们演示了合成通用的酰基自由基的获得方法，可以将芳香族和脂肪族羧酸还原为相应的醛，并具有出色的化学选择性。该协议还通过分子内酰基自由基环化将羧酸转化为杂环和环状酮，从而一步一步形成C–O，C–N和C–C键。
