• CYCLOHEXANE ANALOGUES AS GPR119 AGONISTS

  This invention relates to a series of substituted cyclohexane containing analogues which are agonists of GPR119 intended to treat metabolic diseases mediated by GPR119 including Type I & II diabetes mellitus. Diabetes mellitus is an ever-increasing threat to human health causing various complications (blindness, kidney failure, neuropathy, heart attack, stroke, etc.). Recently it was found that activation of GPR119 which is highly expressed in pancreatic beta cells causes glucose dependent insulin secretion and GLP-1 release. Many pharmaceuticals are currently developing GPR119 agonists and herein we disclose alternative GPR119 agonists. Our invention describes GPR119 agonists having structural Formula (I), pharmaceutically acceptable salt or solvate of Formula (I), isomer or prodrug of Formula (I), and combination therapy of Formula (I) with other anti-diabetic drugs like DPP-IV inhibitors and/or insulin sensitizers.

  这项发明涉及一系列含有替代基的环己烷类似物，这些类似物是 GPR119 激动剂，旨在治疗由 GPR119 介导的代谢性疾病，包括I型和II型糖尿病。糖尿病是对人类健康构成日益增加的威胁，导致各种并发症（失明、肾衰竭、神经病变、心脏病发作、中风等）。最近发现，激活在胰岛素β细胞中高表达的 GPR119 会导致葡萄糖依赖性胰岛素分泌和 GLP-1 释放。许多制药公司目前正在开发 GPR119 激动剂，我们在此披露了替代的 GPR119 激动剂。我们的发明描述了具有结构式（I）的 GPR119 激动剂，结构式（I）的药学上可接受的盐或溶剂，结构式（I）的异构体或前药，以及结构式（I）与其他抗糖尿病药物（如 DPP-IV 抑制剂和/或胰岛素增敏剂）的联合治疗。

  [reaction: see text] A new efficient method for the N-heterocyclization of primary amines with diols catalyzed by a CpIr complex was developed. A variety of five-, six-, and seven-membered cyclic amines were synthesized in good to excellent yields with the formation of only water as a byproduct. A two-step asymmetric synthesis of (S)-2-phenylpiperidine was also achieved using (R)-1-phenylethylamine

  [反应：见正文]开发了一种新的有效方法，用于CpIr配合物催化的伯胺与二醇的N-杂环化。合成了多种五元，六元和七元环状胺，其收率好至极佳，仅形成水作为副产物。使用（R）-1-苯基乙胺作为起始伯胺，还可以实现两步不对称合成（S）-2-苯基哌啶。

  (HB) amination has been expanded to secondary alcohols, which had previously been reported to react only in the presence of large amounts of co-catalysts. A range of cyclic and acyclic secondary alcohols were reacted with aromatic and aliphatic amines giving fair to excellent yields of the substitution products. The catalyst was also able to promote the cyclization of diols bearing a secondary alcohol

  The intramolecular hydroamination of a large variety of non-activated alkenes can be efficiently catalysed by small amounts of lithium bases, providing smoothly and in high yields the corresponding five- and six-membered ring heterocycles. Fused and bridged bicyclic amines, of varying ring sizes, can be readily prepared either by a sequential hydroamination process or by a tandem, double addition reaction
