  • Dehydrative Glycosylation with Activated Diphenyl Sulfonium Reagents. Scope, Mode of <i>C</i>(1)-Hemiacetal Activation, and Detection of Reactive Glycosyl Intermediates
    作者:Brian A. Garcia、David Y. Gin
    DOI:10.1021/ja993595a
    日期:2000.5.1
    The development of a method for direct dehydrative glycosylations with 1-hydroxyglycosyl donors employing the reagent combination of triflic anhydride and diphenyl sulfoxide is described. The one-pot coupling method is a facile process which is applicable to a variety of carbohydrate coupling partners. Oxygen-18-labeling studies are consistent with the first step in carbohydrate activation being the

    reacted with various thiols by irradiation with UV light in the presence of a cleavable photoinitiator. The photoinduced radical-mediated hydrothiolation reactions showed highly varying overall conversions depending not only on the substitution pattern and electron-density of the double bond but also on the nature and substitution pattern of the thiol partner. Out of the applied thiols thiophenol, producing
    通过在可裂解的光引发剂的存在下用紫外线照射,使糖的外环和内环双键以及烯键的末端双键与各种硫醇反应。光诱导的自由基介导的氢硫醇化反应显示出很大变化的总转化率,这不仅取决于双键的取代方式和电子密度,还取决于硫醇配偶体的性质和取代方式。在所施加的硫醇中,产生高度稳定的噻吩基的硫酚对每种烯烃的反应性最低。在大多数情况下,氢硫醇化反应具有完全的区域选择性和立体选择性。将1,2:3,4-二-O-异亚丙基-6-硫代-α- D-吡喃半乳糖成功添加到2,3-不饱和N-乙酰神经氨酸衍生物提供(3→6)-S连接的假二糖,表明带有吸电子取代基的Neu5Ac-2-ene的内环双键在光诱导的硫醇-烯偶联反应中显示出足够的反应性。 。
  • <i>N</i> -Trifluoromethylthiosaccharin/TMSOTf: A New Mild Promoter System for Thioglycoside Activation
    作者:Cian Mc Carthy、Matthias Tacke、Xiangming Zhu
    DOI:10.1002/ejoc.201900265
    日期:2019.4.30
    N‐Trifluoromethylthiosaccharin was used to activate a series of thioglycosides in the presence of catalytic amounts of TMSOTf. Chemoselective activation of ethyl thioglycosides in the presence of phenyl thioglycosides was also achieved under the same conditions.

  • A New Route toexo-Glycals Using the Ramberg−Bäcklund Rearrangement
    作者:Frank K. Griffin、Duncan E. Paterson、Paul V. Murphy、Richard J. K. Taylor
    DOI:10.1002/1099-0690(200204)2002:7<1305::aid-ejoc1305>3.0.co;2-0
    日期:2002.4
    A new route to exo-glycals 4 is described in which glycosyl sulfones 3 are subjected to the Meyers variant of the Ramberg−Bäcklund rearrangement. The conversion of sulfones derived from glucose, galactose, mannose, cellobiose, and ribose into di-, tri-, and tetra-substituted alkenes is reported. Preliminary mechanistic studies of this process are also described. (© Wiley-VCH Verlag GmbH, 69451 Weinheim
    描述了一种通往外糖4的新途径,其中糖基砜3经历了Ramberg-Bäcklund重排的Meyers变体。据报道,衍生自葡萄糖,半乳糖,甘露糖,纤维二糖和核糖的砜转化为二,三和四取代的烯烃。还介绍了此过程的初步机理研究。(©Wiley-VCH Verlag GmbH,69451 Weinheim,Germany,2002)
