  Novel potent neuropeptide Y Y5 receptor antagonists: Synthesis and structure–activity relationships of phenylpiperazine derivatives

  摘要：

  A series of phenylpiperazine derivatives were synthesized and evaluated for their neuropeptide Y (NPY) Y5 receptor antagonistic activities. The benzindane portion of 2 was replaced by I-phenylpiperazine, resulting in novel urea derivative X Subsequent optimization of the phenylpiperazine template by substitution of the phenyl moiety resulted in a series of (2-methanesulfonamidephenyl)piperazine derivatives that showed potent binding affinity and antagonistic activity for the Y5 receptor.

  reactions. However, the substrates were mostly limited to reactive carbonyl compounds (aldehydes and ketones) or carbon‐carbon multiple bonds. Here, we describe the application of newly‐developed chelating bis(tzNHC)‐rhodium complexes (tz=1,2,3‐triazol‐5‐ylidene) for several reductive transformations. With these catalysts, the formal reductive methylation of amines using carbon dioxide, the hydrosilylation

  NHC-铑配合物（NHC = N-杂环卡宾）已被广泛用作氢化硅烷化反应的有效催化剂。但是，底物主要限于反应性羰基化合物（醛和酮）或碳-碳多重键。在这里，我们描述了新开发的螯合双（tz NHC）-铑配合物（tz = 1,2,3-三唑-5-亚烷基）在几种还原转化中的应用。使用这些催化剂，已经在温和的反应条件下实现了使用二氧化碳的胺的正式还原甲基化，酰胺和羧酸的氢化硅烷化以及使用羧酸的胺的还原烷基化。
