Abstract

C-Glycosides represent a privileged class of carbohydrates, which exhibit remarkable biological and pharmaceutical activities. Transition metal-catalyzed cross coupling reaction is a powerful tool for the efficient and rapid construction of C-C bonds. Among various transition-metal catalyzed methods, palladium-catalyzed C-glycosylation is an effective and reliable approach to synthesize C-glycosides, which involves the reaction of glycoyl donors and various reaction partners via C-C glycosidic bond formation under mild conditions with high regio/stero-selectivities. In this review, palladium-catalyzed C-glycosylation reactions are summarized and discussed in detail with the focus on the synthesis of C-aryl glycosides, C-alkyl glycosides, C-alkenyl glycosides, and other functionalized C-glycosides since 2020 to 2024. Some representative synthetic strategies and their transformation application along with reaction mechanisms are also highlighted.

通过钯催化糖基化反应合成 C-糖苷
C-Glycosides 是一类特殊的碳水化合物,具有显著的生物和医药活性。过渡金属催化的交叉偶联反应是高效、快速构建 C-C 键的有力工具。在各种过渡金属催化方法中,钯催化的 C-糖基化是合成 C-糖苷的一种有效而可靠的方法,它涉及糖酰基供体和各种反应物在温和条件下通过 C-C 糖苷键的形成发生反应,具有很高的区域/立体选择性。本综述总结并详细讨论了 2020 年至 2024 年期间钯催化的 C-糖基化反应,重点是 C-芳基糖苷、C-烷基糖苷、C-烯基糖苷和其他功能化 C-糖苷的合成。此外,还重点介绍了一些具有代表性的合成策略及其转化应用以及反应机理。
