  • Deoxygenative Olefination Reaction as the Key Step in the Syntheses of Deoxy and Iminosugars
    作者:Yung Chang Hsu、Jih Ru Hwu
    DOI:10.1002/chem.201201060
    日期:2012.6.18
    Just a spoonful of sugar! A new synthetic strategy involving the use of a deoxygenative olefination reaction as the key step was developed for the preparation of deoxy and iminosugars in their optically active form (see scheme). This strategy has been proven successful by the use of a pentose, hexose, heptose, and disaccharide as the starting materials. Furthermore, it was applied in a formal total

  • A Convenient Route to Higher Sugars by Two-Carbon Chain Elongation Using Wittig/Dihydroxylation Reactions
    作者:Morten Jørgensen、Erik H. Iversen、Robert Madsen

    日期:2001.6.1
    rule and gives high diastereoselectivity (5:1-8:1) when starting from sugars with the 2,3-threo configuration. When starting from sugars with the 2,3-erythro configuration, the diastereoselectivity in the dihydroxylation is low (2:1-2.5:1). As a result, the Wittig/dihydroxylation protocol is most effective for producing higher sugars with the galacto configuration at the reducing end. The two steps can
    维蒂希烯化和二羟基化反应的组合构成了用于将未保护的碳水化合物转化成高级糖的简便的合成方案。Wittig反应是用叔丁基或二苯基甲基酯稳定的膦烷进行的,在大多数情况下,仅有(E)-构型的α,β-不饱和酯是唯一的产物。使用OsO(4)/ NMO以非对映选择性的方式将它们二羟基化。二羟基化反应中的立体化学结果遵循Kishi的经验规律,当从具有2,3-苏式构型的糖开始时,具有很高的非对映选择性(5:1-8:1)。当从具有2,3-赤型构型的糖开始时,二羟基化反应中的非对映选择性低(2:1-2.5:1)。结果是,Wittig /二羟基化方案最有效用于生产还原端为半乳糖构型的高级糖。这两个步骤可以单独执行,也可以一站式执行,效率更高。
