for asymmetric catalysis. Herein, we report the concise synthesis of a Si-centered spirocyclic skeleton, spirobiphenoxasilin-diol (SPOSiOL), and its derived chiral ligands. Using the chemical resolution method, the optical SPOSiOL could be obtained in high yield on a gram scale. Preliminary studies indicated that this ligand scaffold has great potential in transition metal-catalyzed asymmetric reactions
手性配体和催化剂发现的手性结构的开发对于不对称催化至关重要。在此,我们报告了以 Si 为中心的螺环骨架、spirobiphenoxasilin-diol (SPOSiOL) 及其衍生手性配体的简明合成。使用化学拆分方法,可以在克级以高产率获得光学 SPOSiOL。初步研究表明,该配体支架在过渡金属催化的不对称反应中具有巨大潜力。这一发现进一步强调了以 Si 为中心的螺环支架在不对称催化中具有重要价值。
