  受经典胺化反应启发的吡啶和二嗪的选择性 CH 氟化

  摘要：

  氟化吡啶 将氟取代基附加到碳中心通常用于调节药物和农业化学研究中的小分子特性。然而，氟化通常需要使用腐蚀性、危险的试剂。Fier 和 Hartwig (p. 956) 提出了一种异常温和且方便的方案，用于氟化吡啶和相关含氮芳烃中与氮相邻的碳位点。该反应需要用二氟化银处理并在室温下快速进行。温和的氟化方法可以帮助生产医学研究中感兴趣的化合物。氟化杂环广泛存在于药物、农用化学品和材料中。然而，将氟结合到杂芳烃中的反应范围有限并且可能是危险的。我们提出了一种广泛适用且安全的方法，用于使用市售的氟化银 (II) 对吡啶和二嗪中的单个碳氢键进行位点选择性氟化。反应在环境温度下在 1 小时内发生，并且对氮附近的氟化具有唯一的选择性。温和的条件允许获得具有重要医学意义的化合物的氟化衍生物，以及通过随后的氟化物亲核置换制备的一系列 2-取代吡啶。机理研究表明，经典的吡啶胺化途径可适用于广泛范围的氮杂环的选择性氟化。反应在环境温度下在

  synthesized compound (II) for the avoidance of hepatotoxicity. The replacement of the left-hand side benzene with 2-pyridine resulted in the substantial loss of potency. Because poor membrane permeability was responsible for poor potency in vitro, the adjustment of lipophilicity was examined, which resulted in the discovery of dimethyl pyridine derivative (I, DS-6930). In preclinical studies, DS-6930 demonstrated

  为了避免肝毒性，尝试降低先前合成的化合物（II）的亲脂性。用2-吡啶代替左手侧苯导致效力的实质损失。由于差的膜通透性导致体外效价差，因此对亲脂性的调节进行了检查，从而发现了二甲基吡啶衍生物（I，DS-6930）。在临床前研究中，DS-6930表现出较高的PPARγ激动剂效价，且血浆葡萄糖降低明显。DS-6930在体内进行毒理学评估后维持与PPARγ相关的副作用减少，并没有显示出肝毒性。辅助因子募集测定表明，显着募集了一些辅助因子，例如RIP140和PGC1，而几个典型因子并未受到影响。这种选择性辅因子募集是由于DS-6930的独特结合模式引起的。钙盐DS-6930b被认为是有效的胰岛素增敏剂，无水肿，可在T2DM患者中进行临床评估。
