  Hydride-Induced Anionic Cyclization: An Efficient Method for the Synthesis of 6-H-Phenanthridines via a Transition-Metal-Free Process

  摘要：

  A novel procedure for hydride-induced anionic cyclization has been developed. It includes the reduction of a biaryl bromo-nitrile with a nucleophilic aromatic substitution (SNAr). A range of polysubstituted 6-H-phenanthridines were so obtained in moderate to good yield with good substrate tolerance. This method involves a concise transition-metal-free process and was applied to synthesize natural alkaloids.

  摘要：

  [反应：参见正文]使用2,2,6,6-四甲基哌啶锂（LTMP）与三异丙基硼酸酯（B（OiPr）（3））结合进行原位锂化是一种高效且实验简单的制备方法取代的芳基硼酸酯的制备。温和的反应条件允许存在官能团，例如酯或氰基或卤素取代基，这些官能团通常与在芳烃的定向邻位金属化中使用的条件不兼容。芳基硼酸酯与多种芳基卤化物进行了铃木型交叉偶联，以53-94％的收率提供了联芳基。

  2-trimethylsilylphenylboronic acid with internal alkynes is developed for the synthesis of 2,3-disubstituted benzosilole derivatives. A range of functional groups, encompassing ketones, esters, amines, aryl bromides, and heteroarenes, are compatible, which provides rapid access to diverse benzosiloles. Sequential 2-fold coupling enables modular synthesis of asymmetrically substituted 1,5-dihydro-1,5-disila-s-indacene

  开发了铑催化的 2-三甲基甲硅烷基苯基硼酸与内部炔烃的偶联反应，用于合成 2,3-二取代的苯并硅氧烷衍生物。包括酮、酯、胺、芳基溴化物和杂芳烃在内的一系列官能团是相容的，从而可以快速获得各种苯并硅氧烷。顺序 2 倍偶联能够模块化合成不对称取代的 1,5-dihydro-1,5-disila-s-indacene，这是一种有机电子学中的 π 扩展分子。就机理而言，该反应涉及三烷基甲硅烷基中的 C(烷基)-Si 键的断裂，这通常需要极其苛刻的活化条件。包括取代基影响在内的机理研究表明，C-Si 键断裂不会通过超配位硅物种进行，而是通过铑介导的活化过程。还证明了该反应在 Si-手性苯甲硅烷的催化不对称合成中的潜在用途。

  compounds is reported. Compared to the previous approach of installing a complex U-shaped template to achieve a molecular U-turn and assemble the large-sized cyclophane transition state for the remote C-H activation, a synthetically useful phenyl nitrile functional group could also direct remote meta-C-H activation. This reaction provides a useful method for the modification of biaryl compounds because

  报道了一种简单而有效的腈引导的间-CH烯化、乙酰氧基化和联芳基化合物的碘化。与之前安装复杂的U型模板以实现分子掉头并组装大尺寸环芳过渡态以进行远程CH活化的方法相比，合成有用的苯基腈官能团也可以直接远程间位CH活化。该反应为联芳基化合物的改性提供了一种有用的方法，因为腈基可以很容易地转化为胺、酸、酰胺或其他杂环。值得注意的是，从之前使用大环芳腈模板的结果中无法预期联苯腈的远程间位选择性。DFT 计算研究表明，含有配体的 Pd-Ag 异二聚过渡态 (TS) 有利于所需的远程元选择性。对照实验证明了腈基团的定向作用并排除了非定向元-CH激活的可能性。研究发现，取代的 2-吡啶酮配体在协同金属化-去质子化 (CMD) 过程中协助间位 CH 键断裂的关键。

• Novel N-biphenyl-2-ylmethyl 2-methoxyphenylpiperazinylalkanamides as 5-HT7R antagonists for the treatment of depression

  5-HT7 receptor (5-HT7R) is a promising target for the treatment of depression and neuropathic pain. 5-HT7R antagonists exhibited antidepressant effects, while the agonists produced strong anti-hyperalgesic effects. In our efforts to discover selective 5-HT7R antagonists or agonists, N-biphenylylmethyl 2-methoxyphenylpiperazinylalkanamides 1 were designed, synthesized, and biologically evaluated against 5-HT7R. Among the synthesized compounds, N-2'-chlorobiphenylylmethyl 2-methoxyphenylpiperazinylpentanamide 1-8 showed the best binding affinity with a Ki value of 8.69nM and it was verified as a novel antagonist according to functional assays. The compound 1-8 was very selective over 5-HT1DR, 5-HT2AR, 5-HT3R, 5-HT5AR and 5-HT6R and moderately selective over 5-HT1AR, 5-HT1BR and 5-HT2CR. The novel 5-HT7R antagonist 1-8 exhibited an antidepressant effect at a dose of 25mg/kg in the forced swimming test in mice and showed a U-shaped dose-response curve which typically appears in 5-HT7R antagonists such as SB-269970 and lurasidone.
