  一种制备3-甲基-1-苯乙基哌啶-4-酮或1-苯 乙基哌啶-4-酮的方法

  摘要：

  本发公开了一种制备3‑甲基‑1‑苯乙基哌啶‑4‑酮或1‑苯乙基哌啶‑4‑酮的方法。从易得的3‑取代吡啶‑4‑醇出发,与苯乙基‑2‑卤代物成季胺盐后,硼氢化钠选择性还原成烯基醇,再异构化后得到3‑取代‑1‑苯乙基哌啶‑4‑酮。该合成方法简便实用，可操作性强，有利于进一步放大生产。

  The present invention provides conformationally-defined macrocyclic compounds that bind to and/or are functional modulators of the motilin receptor including subtypes, isoforms and/or variants thereof. These macrocyclic compounds, at a minimum, possess adequate pharmacological properties to be useful as therapeutics for a range of disease indications. In particular, these compounds are useful for treatment and prevention of disorders characterized by hypermotilinemia and/or gastrointestinal hypermotility, including, but not limited to, diarrhea, cancer treatment-related diarrhea, cancer-induced diarrhea, chemotherapy-induced diarrhea, radiation enteritis, radiation-induced diarrhea, stress-induced diarrhea, chronic diarrhea, AIDS-related diarrhea, C. difficile associated diarrhea, traveller's diarrhea, diarrhea induced by graph versus host disease, other types of diarrhea, dyspepsia, irritable bowel syndrome, chemotherapy-induced nausea and vomiting (emesis) and post-operative nausea and vomiting and functional gastrointestinal disorders. In addition, the compounds possess utility for the treatment of diseases and disorders characterized by poor stomach or intestinal absorption, such as short bowel syndrome, celiac disease and cachexia. The compounds also have use for the treatment of inflammatory diseases and disorders of the gastrointestinal tract, such as inflammatory bowel disease, ulcerative colitis, Crohn's disease and pancreatitis. Accordingly, methods of treating such disorders and pharmaceutical compositions including compounds of the present invention are also provided.
