    Abstract Application of the Strecker reaction to methyl 6-deoxy-2,3- O -isopropylidene- α - l - lyxo -hexopyranosid-4-ulose resulted in the formation of methyl 4-amino-4-cyano-4,6-dideoxy-2,3- O -isopropylidene- α - l -talopyranoside, methyl 4-amino-4-cyano-4,6-dideoxy-2,3- O -isopropylidene- β - d -allopyranoside and methyl 4-cyano-6-deoxy-2,3- O -isopropylidene- α - l -talopyranoside. Their proportionality
    摘要Strecker反应在甲基6-脱氧-2,3-O-异亚丙基-α-l-lyxo-己喃糖基-4-ulose中的应用导致甲基4-基-4-基-4,6-dideoxy的形成-2,3-O-异亚丙基-α-1-talpyyranoside,甲基4-基-4-基-4,6-dideoxy-2,3- O-异亚丙基-β-d-Allopyranoside和甲基4-cyano-6 -脱氧-2,3-O-异亚丙基-α-1-喃糖苷。它们的比例和产率取决于所使用的反应条件。另外,可以由预先形成的甲基4-基-6-脱氧-2,3-O-有利地制备4-基-4-基-4,6-二脱氧-2,3-O-异亚丙基-α-1-塔拉喃糖苷。异亚丙基-α-1-塔洛喃糖苷。还给出了甲基4-乙酰基-4-基-4,6-二脱氧-2,3-O-异亚丙基-α-1--1-喃糖苷的晶体结构。
  • Tetrazoles of manno- and rhamno- furanoses
    作者:Benjamin G. Davis、Robert J. Nash、Alison A. Watson、Colin Smith、George W.J. Fleet
    DOI:10.1016/s0040-4020(99)00138-6
    日期:1999.4
    The synthesis of [3.3.0] bicyclic tetrazoles derived from D-manno and D-rhamnofuranose starting from D-mannose, and of L-rhamnofuranose starting from L-rhamnose is described. The key step in the formation of all three examples of this novel class of sugar mimics is an intramolecular [1,3]-dipolar cycloaddition of azide and nitrile moieties.
    描述了衍生自D-甘露糖D-甘露糖和D-鼠李呋喃糖的[3.3.0]双环四唑和源自L-鼠李糖的L-鼠李呋喃糖的合成。形成这种新型糖模拟物的所有三个实例的关键步骤是叠氮化物和腈部分的分子内[1,3]-偶极环加成反应。

  • Synthesis of Disaccharides Containing 6-Deoxy-a-L-talose as Potential Heparan Sulfate Mimetics
    作者:Jon K. Fairweather、Ligong Liu、Tomislav Karoli、Vito Ferro
    DOI:10.3390/molecules17089790
    日期:——
    A 6-deoxy-a-L-talopyranoside acceptor was readily prepared from methyl a-L-rhamnopyranoside and glycosylated with thiogalactoside donors using NIS/TfOH as the promoter to give good yields of the desired a-linked disaccharide (69–90%). Glycosylation with a 2-azido-2-deoxy-D-glucosyl trichloroacetimidate donor was not completely stereoselective (a:b = 6:1), but the desired a-linked disaccharide could be isolated in good overall yield (60%) following conversion into its corresponding tribenzoate derivative. The disaccharides were designed to mimic the heparan sulfate (HS) disaccharide GlcN(2S,6S)-IdoA(2S). However, the intermediates readily derived from these disaccharides were not stable to the sulfonation/deacylation conditions required for their conversion into the target HS mimetics.
    从甲基 a-L 鼠李糖苷中很容易制备出 6-脱氧-a-L-喃塔喃糖苷受体,并使用 NIS/TfOH 作为促进剂代半乳糖苷供体进行糖基化,从而获得了所需的 a-连接双糖(69-90%)。用 2-叠氮-2-脱氧-D-葡萄糖基三乙酰亚酸供体进行糖基化并不完全具有立体选择性(a:b = 6:1),但将其转化为相应的三苯甲酸酯衍生物后,可分离出所需的 a 链二糖,总产率高达 60%。设计这些二糖的目的是模仿硫酸肝素(HS)二糖 GlcN(2S,6S)-IdoA(2S)。然而,这些二糖容易衍生出的中间体在磺化/脱乙酰化条件下并不稳定,而磺化/脱乙酰化条件是将它们转化为目标 HS 拟效物所必需的。
  • Synthesis of 4-thio-l-rhamnofuranose
    作者:Patricia A. Zunszain、Oscar Varela

    日期:1991.12
    HO-4 group of methyl 6-deoxy-2,3- O -isopropylidene-α- l -talopyranoside ( 1 ) afforded the mesyl ( 2 ), nosyl ( 3 ), and trifyl ( 4 ) derivatives. Attempted nucleophilic displacement of the sulfonyloxy group of 2, 3, and 4 by potassium thiocyanate was unsuccessful. Removal of the isopropylidene acetal from 3 and 4 gave the corresponding 4-nosylate ( 5 ) and 4-triflate ( 6 ) of methyl 6-deoxy-α- l -talopyranoside
    摘要甲基6-脱氧-2,3-O-异亚丙基-α-1-塔拉喃糖苷的HO-4基团进行磺酰化(1)得到甲磺酰基(2),壬基(3)和三甲酰基(4)衍生物。尝试用硫氰酸钾亲核取代2、3和4的磺酰氧基是不成功的。从3和4除去异亚丙基乙缩醛得到相应的4-脱甲磺酸酯(5)和4-三氟甲磺酸酯(6),其为甲基6-脱氧-α-1-塔拉喃糖苷。在乙酰化时,5和6分别得到2,3-二-O-乙酰基衍生物7和8。用N,N-二甲基甲酰胺中的硫氰酸钾对7和8中的磺酸进行亲核取代,从而在28和52中得到甲基2,3-二-O-乙酰基-4-脱氧-4-基-α-1-鼠李糖喃糖苷(9) %收率分别。还原9的基,然后进行乙酰分解,得到1,2,3-三-O-乙酰基-4-S-乙酰基-4-代-α-dl-鼠李糖喃糖苷(12),其在脱乙酰基作用下产生4-代-1-鼠李糖(13)。乙酰化13得到4--1-鼠李糖呋喃糖的α(14)和β(15)四乙酸酯。
