  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.
