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。

synthesis, photophysics and photochemistry of a family of molecular switches inspired by the green fluorescent protein (GFP) chromophore is presented. These compounds can be synthesized in one step and good yields, their photophysical properties may be tuned by the substituents, solvent and wavelength of irradiation, and they show very efficient and fast photoisomerization. Furthermore, their high thermal
