  含喹喔啉N-氧化物的有效血管紧张素II受体拮抗剂：合成，生物学性质和构效关系。

  摘要：

  制备了一系列新的含喹喔啉杂环的血管紧张素Ⅱ受体拮抗剂类似物。该杂环通过氧原子接头而不是碳原子与联苯部分偶联。这些类似物中的许多表现出非常有效的活性和长的作用持续时间。有趣的是，如化合物5与30的比较，N-氧化物喹喔啉类似物比未氧化的喹喔啉更有效。为了提高口服活性，将这些化合物的羧酸功能转化为双酯。这种变化确实导致口服活性的改善，如化合物44所示。

  磺酰氟的脱磺化 Suzuki-Miyaura 偶联。

  摘要：

  磺酰氟已成为获得磺酰化衍生物的强大“点击”亲电试剂。然而，它们对 CC 键形成转化相对惰性，特别是在过渡金属催化下。在这里，我们描述了芳基磺酰氟作为 Pd 催化的 Suzuki-Miyaura 交叉偶联的亲电试剂的条件。这种脱磺化交叉偶联在不存在碱的情况下选择性地发生，并且不寻常地，甚至在存在强酸的情况下也会发生。两种生物活性化合物类似物的不同一步合成展示了磺酰氟的扩展反应性，包括 S-Nu 和 CC 键的形成。机理实验和 DFT 计算表明，氧化加成发生在 CS 键上，然后脱磺化形成促进金属转移的 Pd-F 中间体。

  Treatment of anti alkyl o-biaryl ketoximes and anti aryl o-biaryl ketoximes with Tf2O at 120 °C, followed by quenching with Et3N gave 6-alkylphenanthridines and 6-arylphenanthridines in good yields, respectively. These reactions proceeded through the O-triflation of the ketoximes, the Beckmann rearrangement, and the electrophilic cyclization of the formed nitrilium group onto the aromatic ring. © 2021
