  摘要：

  据报道，钯( II )/降冰片烯协同催化可实现频哪醇芳基硼酸盐或杂芳基硼酸盐的氧化还原中性邻位-C -H胺化，用于合成结构多样的苯胺。该方法具有可扩展性、稳健性（耐空气和湿气）、不含膦配体，并且与多种功能兼容。这些实用的特征使得该反应适合工业界。使用这种方法可以很容易地生产大量合成上非常有用的卤代苯胺，这些卤代苯胺通常无法通过其他过渡金属催化的胺化来制备。特别是，证明了频哪醇芳基硼酸盐和芳基碘化物之间的正交反应性。初步的氘标记研究揭示了该过程的氧化还原中性原质子化机制，这必将为该领域的未来发展带来启发。总体而言，该方法的范围极其广泛（47 个示例）和可靠性，加上频哪醇芳基硼酸酯的广泛可用性，使该化学成为现有苯胺合成方法的宝贵补充。

  (杂)芳烃与双(三氟甲基)过氧化物的自由基C−H三氟甲氧基化

  摘要：

  三氟甲氧基化（杂）芳烃引起了多个学科的极大兴趣，特别是在农业化学和药物化学领域。 (杂)芳烃的自由基CH-三氟甲氧基化是制备此类化合物的一种有吸引力的方法，但现有OCF 3自由基源的高成本和低原子经济性使得它们不适合大规模合成三氟甲氧基化结构单元。在此，我们引入双（三氟甲基）过氧化物（BTMP，CF 3 OOCF 3 ）作为一种实用且高效的三氟甲氧基化试剂，可以从廉价的散装化学品中轻松获得。使用可见光光氧化还原或 TEMPO 催化，可以在温和条件下直接从未活化的芳烃中以良好的产率制备三氟甲氧基化芳烃。此外，TEMPO 催化可以一步合成有价值的吡啶衍生物，而这些衍生物之前是通过多步方法制备的。

  method enables non‐directed functionalization of C−H bonds on a range of substrates, providing access to aryl trifluoromethyl ethers. This light‐driven process is distinctly different from conventional procedures and occurs through an OCF3 radical mechanism mediated by a photoredox catalyst, which triggers an N−O bond fragmentation. The pyridinium‐based trifluoromethoxylation reagent is bench‐stable and

  Gram-negative bacteria pose a major challenge in antibiotic drug discovery because their cell envelope presents a permeability barrier that affords high intrinsic resistance to small-molecule drugs. The identification of correlations between chemical structure and Gram-negative permeability would thus enable development of predictive tools to facilitate antibiotic discovery. Toward this end, have advanced

  革兰氏阴性细菌对抗生素药物的发现提出了重大挑战，因为它们的细胞包膜呈现出渗透性屏障，对小分子药物具有高度的内在耐药性。因此，识别化学结构和革兰氏阴性渗透性之间的相关性将有助于开发预测工具，以促进抗生素的发现。为此，我们提出了一种文库设计范例，其中使用统一的试剂组在不同的区域异构体位置对各种化学支架进行功能化。这种设计能够解耦支架、区域化学和取代基对这些分子的革兰氏阴性渗透性的影响。基于我们最近合成的 C2 取代的磺酰胺腺苷文库，我们现在开发了一种有效的合成路线，用于合成区域异构 C8 取代的同系物的类似文库。 C8 库对抗生素相关化学空间区域进行采样，该区域与 C2 库所处理的区域类似，但与类似取代的恶唑烷酮库采样的区域不同。在初步分析中测试了所选分子的积累情况，为将来对这些库进行全面比较评估奠定了基础。
