  • Synthesis of Anomeric Sulfimides and Their Use as a New Family of Glycosyl Donors
    作者:Florence Chéry、Stéphanie Cassel、Hans Peter Wessel、Patrick Rollin
    DOI:10.1002/1099-0690(20021)2002:1<171::aid-ejoc171>3.0.co;2-7
    日期:2002.1
    We introduce a convenient synthesis of anomeric sulfimides, the ability of which to act as glycosyl donors has been tested with various thiophilic reagents and acceptors.
    我们介绍了一种方便的异头磺酰亚胺合成方法,其作为糖基供体的能力已经用各种亲试剂和受体进行了测试。
  • A convenient synthesis of the core trisaccharide of the N-glycans
    作者:Zhichao Lu、Ning Ding、Wei Zhang、Peng Wang、Yingxia Li
    DOI:10.1016/j.tetlet.2011.04.060
    日期:2011.6
    A convenient synthesis of the core trisaccharide of the N-glycans was described. Orthogonal one-pot glycosylation of three monosaccharide building blocks was performed to furnish β-glucosyl chitobiose, which was then transformed to β-mannosyl chitobiose by intramolecular epimerization of the C-2 position of the β-glucoside. The key glucosyl donor 7c with differentiated 2,3-OH was prepared following
    描述了N-聚糖的核心三糖的方便合成。进行三个单糖结构单元的正交一锅糖基化反应以提供β-葡萄糖壳二糖,然后通过分子内差向异构化β-葡萄糖苷的C-2位将其转化为β-甘露糖壳二糖。遵循4,6 - O-亚苄基保护的1,2-原酸酯策略,制备了具有分化的2,3-OH的关键葡糖基供体7c。
  • Synthesis of flaccidoside II, a bidesmosidic triterpene saponin isolated from Chinese folk medicine Di Wu
    作者:Shuihong Cheng、Yuguo Du、Feihong Bing、Guobin Zhang
    DOI:10.1016/j.carres.2007.11.015
    日期:2008.2
    A total synthesis of flaccidoside II, 3-O-alpha-L-rhamnopyranosyl-(1-->2)-beta-D-xylopyranosyloleanolic acid 28-O-alpha-L-rhamnopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside, isolated from Chinese folk medicine Di Wu, has been accomplished from building blocks isopropyl 2-O-acetyl-3,4-di-O-benzoyl-1-thio-beta-D-xylopyranoside, 2,3,4-tri-O-benzoyl-alpha-L-rhamnopyranosyl trichloroacetimidate

  • Visible-Light-Mediated Oxidative Debenzylation Enables the Use of Benzyl Ethers as Temporary Protecting Groups
    作者:Cristian Cavedon、Eric T. Sletten、Amiera Madani、Olaf Niemeyer、Peter H. Seeberger、Bartholomäus Pieber
    DOI:10.1021/acs.orglett.0c04026
    日期:2021.1.15
    The cleavage of benzyl ethers by catalytic hydrogenolysis or Birch reduction suffers from poor functional group compatibility and limits their use as a protecting group. The visible-light-mediated debenzylation disclosed here renders benzyl ethers temporary protective groups, enabling new orthogonal protection strategies. Using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as a stoichiometric or
    通过催化氢解或 Birch 还原裂解苄基醚存在官能团相容性差的问题,限制了它们作为保护基团的用途。本文公开的可见光介导的脱苄基作用使苄基醚成为临时保护基团,从而实现新的正交保护策略。使用 2,3-二氯-5,6-二氰基-1,4-苯醌 (DDQ) 作为化学计量或催化光氧化剂,可以在叠氮化物、烯烃和炔烃存在下裂解苄基醚。在连续流动中,反应时间可以从几小时缩短至几分钟。
  • An efficient method for the preparation of glycosides with a free C-2 hydroxyl group from thioglycosides
    作者:Hai Yu、Harry E. Ensley
    DOI:10.1016/j.tetlet.2003.09.230
    日期:2003.12
    A new and efficient method to produce glycosides with a free C-2 hydroxyl group through 1,2-acyl group migration which occurs during the hydrolysis of 4,6-benzylidene protected thioglycosides has been developed. The acyl transfer products allow for further elaboration.
    已经开发了一种新的有效方法,其通过在4,6-亚苄基保护的代糖苷的解过程中发生的1,2-酰基迁移来产生具有游离C-2羟基的糖苷。酰基转移产物允许进一步加工。
