    Stereospecific Synthesis of 1,2-cis Glycosides by Vinyl-Mediated IAD
    摘要:
    (GRAPHICS)Stereospecific 1,2-cis glycosylation of 2-O-vinyl thioglycosides, synthesized from the corresponding alcohols by Ir-catalyzed transvinylation with vinyl acetate, is achieved by iodine-mediated tethering of a range of primary and secondary carbohydrate acceptors, followed by intramolecular aglycon delivery (IAD). The use of such an intramolecular glycosylation strategy furnishes the desired alpha-gluco and beta-manno disaccharides in an entirely stereoselective manner.

    C-2醚功能在丁腈溶剂指导的糖基化反应中的相邻基团参与
    摘要:
    当在腈溶剂混合物中进行反应时,已发现在C-2羟基处的醚保护功能在糖基化中起参与作用。参与机制基于C-2醚功能的氧原子的孤电子对和腈分子以顺式排列时的分子内相互作用。形成一个1,2-顺式糖基恶唑啉鎓中间体。这种参与,再加上糖基供体的异头作用,赋予糖基化较高的1,2-反式选择性。该概念的进一步应用导致了α-(1→5)-阿拉伯低聚物的高效制备。

    An efficient and concise method for the construction of various O‐glycosidic bonds by a palladium‐catalyzed reaction with a 3‐O‐picoloyl glucal has been developed. The stereochemistry of the anomeric center derives from either an inner‐sphere or outer‐sphere pathway. Harder nucleophiles, such as aliphatic alcohols and sodium phenoxides give β‐products, and α products result from using softer nucleophiles
