4-Silapiperidine and 4-silapiperidinium derivatives: syntheses and structural characterization
摘要:
A series of novel 4-silapiperidine and 4-silapiperidinium derivatives, with two silicon-bound aryl groups and various N-organyl groups, have been synthesized and structurally characterized (solution H-1, C-13, F-19, and Si-29 NMR spectroscopy; eight crystal structure analyses). These synthetic and structural investigations provide the basis for the development of novel silicon-based drugs containing, a 4-silapiperidine or 4-silapiperidinium skeleton. (C) 2004 Elsevier B.V.

Notably, each member of the homologous series of amides Ph(CH2)nCONMe2 gives rise to a substantially different product: when n= 0, the reaction is normal, and the yield of the alph]-silylamine 20e is high; when n=1, proton transfer in the intermediate anion 64 and displacement of the phenyl group leads to the silaindane 66; when n=2, fragmentation of the intermediate anion 80, and capture

A simple and efficient two-step method for the synthesis of silacyclohexanones starting from bis(bromoethylsilanes) using TosMIC is presented. The prepared silacyclohexanones were transformed to nine different heterocycles with silicon incorporation. In addition, the developed methodology was used for the synthesis of a sila analogue of the HDAC6 inhibitor tubastatin A.
提出了一种使用 TosMIC以双(溴乙基硅烷)为原料合成硅杂环己酮的简单而有效的两步法。将制备的硅杂环己酮转化为九种不同的硅掺入杂环。此外,所开发的方法还用于合成 HDAC6 抑制剂图巴他汀 A 的 sila 类似物。
