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.

A B(C6F5)3-catalyzed controllable inter/intra-/intermolecular Si–Cbond formation process has been developed from trihydrosilane and dienamide with alkenes, anilines, or aryl iodides. A variety of 1,4-azasilinanes have been generated with diverse exo-cyclic heteroleptic disubstitutions on silicon, thereby expanding the range of silaazacyclic rings available for the discovery of silicon-containing drugs
AB(C 6 F 5 ) 3催化的可控分子间/分子内/分子间Si-C键形成过程是由三氢硅烷和二烯酰胺与烯烃、苯胺或芳基碘化物开发而成。已经通过硅上的多种外环杂配取代生成了多种1,4-氮杂硅烷,从而扩大了可用于发现含硅药物的硅氮杂环的范围。
