  Synthesis and SAR investigations of novel 2-arylbenzimidazole derivatives as melanin-concentrating hormone receptor 1 (MCH-R1) antagonists

  摘要：

  Compounds containing 2-arybenzimidazole ring systems linked to arylpiperidines were synthesized and evaluated as MCH-R1 antagonists. The results of structure-activity relationship studies led to the identification of compound 4c as a potent MCH-R1 antagonist (IC50 = 1 nM). This compound also has good metabolic stability, and favorable pharmacokinetic and brain penetration properties. However 4c was found to be potent inhibitor of the hERG potassium channel.

  rylimidazoles with iodonium ylides leading to substituted tetracyclic and pentacyclic bridgehead N-heterocycles, wherein iodonium ylide acts as a carbene precursor. For the first time, iodonium ylide proceeds through a Ru–carbenoid intermediate. Further, the synthetic utility of this protocol was successfully shown for gram-scale synthesis and useful synthetic transformations.

  在此，我们公开了一种有效的钌催化的 2-芳基苯并咪唑/2-芳基咪唑与碘鎓叶立德的 C-H 官能化，产生取代的四环和五环桥头 N-杂环，其中碘鎓叶立德作为卡宾前体。碘鎓叶立德第一次通过 Ru-carbenoid 中间体进行。此外，该协议的合成效用成功地展示了克级合成和有用的合成转换。
