  Antiallergic agents. 2. N-(1H-Tetrazol-5-yl)-6-phenyl-2-pyridinecarboxamides

  摘要：

  A new series of N-(1H-tetrazol-5-yl)-6-phenyl-2-pyridinecarboxamides was prepared to determine the effects of substituents on the benzene and pyridine rings on antiallergic activity in the rat passive cutaneous anaphylaxis (PCA) assay after oral administration. One member of this series, N-(1H-tetrazol-5-yl)-4-methyl-6-[4-(methylamino)-phenyl]-2- pyridinecarboxamide (231), has an ED50 value of 0.8 mg/kg po and is 85 times more potent than disodium cromoglycate (DSCG) on intravenous administration. Further evaluation of 231 as a clinically useful antiallergic agent is in progress.

  通过恶嗪基吡啶中间体对吡啶进行 C-H 官能化：在酸性条件下切换为对位选择性

  摘要：

  吡啶的对位选择性 C-H 官能化具有重要价值，但仍不成熟。在易于调节的条件下对吡啶进行位点可切换的 C-H 官能化可加快药物开发。我们最近报道了一种通过恶嗪吡啶中间体对吡啶进行间-C-H功能化的氧化还原中性脱芳构化-重芳构化策略。在这里，我们证明这些恶嗪吡啶中间体只需切换到酸性条件即可进行高度对位选择性官能化。多种对烷基化和芳基化吡啶是通过自由基和离子途径制备的。这些温和且无催化剂的方法适用于使用吡啶作为限制试剂的药物的后期对位官能化。吡啶的连续间位、对位双官能化也可以通过依赖于恶嗪吡啶的 pH 依赖性反应性的完全区域控制来实现。

  perspective and is amenable to a broad substrate scope for carboxylic acids and pyridines containing oxidatively sensitive functionalities that do not hold up to other procedures. The strategy offers a practical approach for the C4-selective pyridylation of a diverse range of primary, secondary, and tertiary carboxylic acids and amino acids with various functional groups under mild, metal-free conditions

  杂芳烃的位点选择性 C-H 官能化对于生物活性分子的快速修饰很重要。在此，我们报道了一种有效的光催化平台，用于在外部无氧化剂条件下使用烷基羧酸作为烷基化剂在 C4 位上对吡啶进行可见光介导的 C-H 烷基化。重要的是，发布的N中心自由基可以作为单电子转移（SET）氧化的有效氧化剂，从而有效地再生光催化剂。这种光催化系统从机械学的角度来看很有吸引力，并且适用于含有氧化敏感官能团的羧酸和吡啶的广泛底物范围，这些官能团不适合其他程序。该策略为在温和、无金属条件下对各种具有不同官能团的伯、仲和叔羧酸和氨基酸进行 C4 选择性吡啶化提供了一种实用的方法。

  The present invention discloses a phosphorescent tris-chelated transition metal complex comprising i) two identical carbon-nitrogen (ĈN) or nitrogen-nitrogen (N̂N) chromophoric ligands being incorporated into a coordination sphere thereof with a transition metal, and one carbon-phosphorus (ĈP) chelate being incorporated into the coordination sphere; or ii) one carbon-nitrogen (ĈN) or nitrogen-nitrogen (N̂N) chromophoric ligand forming a coordination sphere thereof with a transition metal, and two identical carbon-phosphorus (ĈP) chelates being incorporated into the coordination sphere, wherein the metal is iridium, platinum, osmium or ruthenium, and the chromophoric ligands possess a relatively lower energy gap in comparison with that of the non-chromophoric chelate, the latter afforded an effective barrier for inhibiting the ligand-to-ligand charge transfer process, so that bright phosphorescence can be observed. The architecture and energy gap of the present molecular designs are suitable for generation of high efficiency blue, green and even red emissions.

  The present invention provides a series of phosphorescent transition metal complexes having a facially arranged, carbon-phosphorus-carbon (ĈP̂C) tridentate chelate, alone with one monoanionic bidentate chromophoric chelate (either ĈN or ÂN) and one arbitrary charge neutral chelate (L), or with one charge neutral bidentate chromophoric chelate (N̂N) and one arbitrary anionic ligand (X); all of them can be used to generate high efficiency photo-induced phosphorescence at room temperature, as well as bright electroluminescence upon employment of these materials in the fabrication of organic light-emitting devices.
