  催化不对称还原三氟烷基化和非对映选择性还原对映选择性合成仲β-三氟甲醇

  摘要：

  氟化基序经常出现在药物和农用化学品中。将含氟基序纳入候选药物以优化药物研发中的先导药物已成为一种强大的工具。具有三氟甲基（CF 3−) 立体生成碳组已积累了广泛的研究成果。与其经过充分探索的具有生物活性的甲基对应物不同，具有相邻立体中心的 β-三氟甲基化醇的不对称结构仍然难以捉摸。通过逆合成分析，我们假设随着羰基的顺序还原，手性 α-三氟甲基化酮的初始构建可以以一种简单的一锅方式提供所需的产品。在此，我们开发了第一个镍催化不对称还原交叉偶联三氟烷基化酰氯的实例，用于对映选择性合成各种α-三氟甲基化酮。这些α-三氟甲基化酮的一锅还原提供了相应的带有β-CF 3的醇-取代的立体碳具有优异的非对映选择性和完全的对映选择性保留。该系统表现出高产率/对映选择性、温和的条件和良好的官能团相容性。该方法的实用性还通过应用生物活性复杂分子的不对称后期三氟烷基化来说明，揭示了开发含 CF 3手性药物的巨大潜力。

• Palladium‐Catalyzed Chlorocarbonylation of Aryl (Pseudo)Halides Through In Situ Generation of Carbon Monoxide
  作者：Philip Boehm、Sven Roediger、Alessandro Bismuto、Bill Morandi

  DOI：10.1002/anie.202005891

  日期：2020.10.5

  efficient palladium‐catalyzed chlorocarbonylation of aryl (pseudo)halides that gives access to a wide range of carboxylic acid derivatives has been developed. The use of butyryl chloride as a combined CO and Cl source eludes the need for toxic, gaseous carbon monoxide, thus facilitating the synthesis of high‐value products from readily available aryl (pseudo)halides. The combination of palladium(0), Xantphos

  已经开发了一种有效的钯催化的芳基（假）卤化物的氯羰基化反应，该反应可以使用多种羧酸衍生物。使用丁酰氯作为CO和Cl的混合来源，就不需要有毒的气态一氧化碳，从而促进了从容易获得的芳基（伪）卤化物合成高价值产品的需求。钯（0），黄药和胺碱的组合对于促进这种广泛适用的催化反应至关重要。总体而言，该反应可通过原位生成的芳酰氯的转化获得多种含羰基的产物。结合实验和计算研究，可以支持涉及原位生成CO的反应机理。

  The direct carboxylation of inert aryl C−H bond catalyzed by abundant and cheap nickel is still facing challenge. Herein, we report the Ni-catalyzed direct carboxylation of aryl C−H bonds in benzamides under 1 atm of CO2 to afford various methyl carboxylates or phthalimides, dealing with different post-processing. The reaction displays excellent functional group tolerance and affords moderate to high
