  4-Aminoquinolines:  Novel Nociceptin Antagonists with Analgesic Activity

  摘要：

  Small-molecule nociceptin antagonists were synthesized to examine their therapeutic potential. After a 4-aminoquinoline derivative was found to bind with the human ORL1 receptor, a series of 4-aminoquinolines and related compounds were synthesized and their binding was evaluated. Elucidation of structure-activity relationships eventually led to the optimum compounds. One of the se compounds, N-(4-amino-2-methylquinolin-6-yl) -2-(4-ethylphenoxymethyl)benzamide hydrochloride (11) not only antagonized nociceptin-induced allodynia in mice but also showed analgesic effect in a hot plate test using mice and in a formalin test using rats. Its analgesic effect was not antagonized by the opioid antagonist naloxone. These results indicate that this nociceptin antagonist has the potential to become a novel type of analgesic that differs from mu -opioid agonists.

  A copper-catalyzed amino lactonization of unsaturated carboxylic acids has been achieved as well as the analogous intermolecular three-component amino oxygenation of olefins. The transformation features mild conditions and a remarkably broad substrate scope, offering a novel and efficient approach to construct a wide range of amino lactones as well as 1,2-amino alcohol derivatives.

  This work emphasizes the synthesis of substituted vinyl arenes by reductive coupling of aryl halides with vinyl bromides under mild and easy‐to‐operate nickel‐catalyzed reaction conditions. A broad range of aryl halides, including heteroaromatics, and vinyl bromides were employed to yielding products in moderate to excellent yields with high functional‐group tolerance. The nickel‐catalytic system displays

  这项工作强调了在温和且易于操作的镍催化反应条件下，通过芳基卤化物与乙烯基溴的还原偶联来合成取代的乙烯基芳烃。广泛使用的芳基卤化物，包括杂芳族化合物和乙烯基溴化物，以中等至优异的收率生产了具有高官能团耐受性的产品。镍催化系统在两个C（sp 2）-卤化物偶合体之间显示出良好的化学选择性，从而证明了不同于其他逐步方案的机理途径。

  alkenyl bromides, (E)-configured vinyl arenes or dienes are formed exclusively. Mechanistic studies show that this selectivity is achieved because the (E)-configured alkenyl bromides undergo a smooth coupling, whereas the (Z)-isomers are rapidly eliminated with the formation of alkynes.

  在[对-异丙基）RuCl 2 ] 2的存在下，（E）-构型的烯基溴化物与芳族羧酸盐偶合形成邻-乙烯基苯甲酸。这种C–H乙烯基化无需任何活化的膦配体就可以高产率进行，并且具有出色的官能团耐受性。从烯基溴化物的常见（E / Z）混合物开始，仅形成（E）构型的乙烯基芳烃或二烯。机理研究表明，实现这种选择性的原因是，（E）-构型的烯基溴化物经历了平滑的偶联，而（Z异构体会随着炔烃的形成而迅速消除。

  strained olefins in trans‐cyclooctenes serve as efficient catalysts for halolactonizations, including bromolactonizations and iodolactonizations. The trans‐cyclooctene framework is essential for excellent catalytic performance, and the substituents also play important roles in determining efficiency. These results are the first demonstration of catalysis by a trans‐cyclooctene.
