played an important role in organic synthesis. Since they contain many stereocenters, they have been widely used as chiral-pool starting materials. Herein, we report the asymmetric formal synthesis of (–)-swainsonine, which exhibits anticancer and immunosuppressive activities and inhibits lysosomal α-mannosidase activity, from d-mannose and d-arabinose. The synthesis utilized Zn-mediated Bernet–Vasella
碳水化合物在有机合成中发挥了重要作用。由于它们含有许多立体中心,因此它们已被广泛用作手性池起始材料。在此,我们报告了 (–)-swainsonine 的不对称形式合成,该合成具有抗癌和免疫抑制活性并抑制溶酶体 α-甘露糖苷酶活性,来自d-甘露糖和d-阿拉伯糖。该合成利用 Zn 介导的 Bernet-Vasella 反应、Horner-Wadsworth-Emmons 烯化和 Grubbs 烯烃复分解作为关键反应。
