  Synthesis of 4-Silacyclohexan-1-ones and (4-Silacyclohexan-1-yl)amines Containing the Silicon Protecting Groups MOP (4-Methoxyphenyl), DMOP (2,4-Dimethoxyphenyl), or TMOP (2,4,6-Trimethoxyphenyl): Versatile Si- and C-Functional Building Blocks for Synthesis

  摘要：

  The 4-silacyclohexanones 1-6 were prepared in convenient multistep syntheses, starting from MeSi(OMe)(3) and PhSi(OMe)(3), respectively. Cleavage of the 4-methoxyphenyl (MOP), 2,6-dimethoxyphenyl (DMOP), and 2,4,6-trimethoxyphenyl (TMOP) protecting groups of 4-6 by treatment with HCl/Et2O in CH2Cl2 at 20 degrees C gives the 4-chloro-4-silacyclohexanone 13. Reductive amination of 1-6 with NH3 or i-PrNH2 yields the respective (4-silacyclohexan-1-yl)amines 7-12. Compounds 1-12 and all new precursors synthesized were characterized by elemental analyses (C, H, N) or mass spectrometric investigations (ESI-HRMS) and by NMR spectroscopic studies (H-1, C-13, Si-29). Compounds 1, 3, 5, and 6 and the precursors (MeO)(2)SiPh-(TMOP) (21) and (CH2=CH)(2)SiPh(TMOP) (27) were additionally characterized by single-crystal X-ray diffraction. Compounds 1-12 with their Si- and C-functional groups represent versatile building blocks for synthesis.

  The GPR81 and GPR109A receptors mediate antilipolytic effects and are potential drug targets for the treatment of metabolic disorders such as dyslipidemia and type 2 diabetes. There is still a need to identify potent GPR81 agonists as pharmacological tools. A high‐throughput screen identified an acylurea‐based GPR81 agonist lead series, with activities at the GPR109A receptor as well. To expand the

  GPR81和GPR109A受体介导抗脂解作用，并且是治疗代谢异常（例如血脂异常和2型糖尿病）的潜在药物靶标。仍然需要确定有效的GPR81激动剂作为药理学工具。高通量筛选确定了基于酰脲的GPR81激动剂先导系列，同时对GPR109A受体也有活性。为了扩大化学范围并探索药理作用和药代动力学后果，一系列结构相关的有机硅化合物与6-sila-4、5、6、7-四氢苯并[ d]合成]噻唑骨架并研究其理化性质[辛醇/水分配系数（pH 7.4），在HBSS缓冲液中的溶解度（pH 7.4）]，对大鼠GPR81和GPR109A受体的激动作用以及在人肝微粒体和大鼠中的固有清除率肝细胞。这些有机硅化合物的直接合成为上述GPR81激动剂铅系列的化学范围提供了有价值的扩展，提供了效能和功效SAR，并产生了具有超微摩尔GPR81效能的化合物。这项工作支持将硅化学纳入药物化学工具箱的价值。
