  • Gold(I)-catalyzed synthesis of β-Kdo glycosides using Kdo ortho-hexynylbenzoate as donor
    作者:Xuemeng Mi、Qixin Lou、Wenjing Fan、Liqin Zhuang、You Yang
    DOI:10.1016/j.carres.2017.04.021
    日期:2017.8
    A gold(I)-catalyzed glycosylation of Kdo with glycosyl ortho-hexynylbenzoate as donor is reported. The couplings of Kdo ortho-hexynylbenzoate with a set of alcohols promoted by PPh3AuOTf afford Kdo glycosides with good β-selectivities. This glycosylation method allows for the synthesis of β-Kdo monosaccharide with a C5 linker at the reducing end for subsequent conjugation to carrier proteins and arrays
    报道了(I)以糖基邻己基苯甲酸酯作为供体的Kdo的糖基化。Kdo邻己基苯甲酸酯与PPh3AuOTf促进的一组醇的偶联为Kdo糖苷提供了良好的β选择性。该糖基化方法允许合成在还原端具有C5接头的β-Kdo单糖,用于随后与载体蛋白和阵列的缀合。
  • Synthesis of 3-<i>C</i>-Branched Kdo Analogues via Sonogashira Coupling of 3-Iodo Kdo Glycal with Terminal Alkynes
    作者:Wenjing Fan、Yan Chen、Qixin Lou、Liqin Zhuang、You Yang
    DOI:10.1021/acs.joc.8b00356
    日期:2018.6.1
    A highly efficient approach for the synthesis of 3-C-branched mono- and di-3-deoxy-d-manno-oct-2-ulosonic acid (Kdo) enyne analogues is developed for the first time based on Sonogashira coupling of terminal alkynes with 3-iodo Kdo glycal obtained by the NIS/TMSOTf-promoted one-step reaction from peracetylated Kdo ethyl ester. Further transformation of 3-C-branched mono- and di-Kdo enyne analogues by
    为3-合成的高度有效的方法Ç -支化的单-和二-3-脱氧d -甘露-辛-2-糖酸(KDO)烯炔类似物是基于的Sonogashira首次末端炔的偶联开发NIS / TMSOTf通过过乙酰化的Kdo乙酯促进的一步反应制得的3-Kdo糖。通过不对称氢化和皂化进一步转化3- C-支化的单-和二-Kdo烯炔类似物,以立体控制方式提供了2-脱氧-β-羧基Kdo类似物。
  • Stereoselective Synthesis of β-<i>C</i>-Glycosides of 3-Deoxy-<scp>d</scp>-<i>manno</i>-oct-2-ulosonic Acid (Kdo) via SmI<sub>2</sub>-Mediated Reformatsky Reactions
    作者:Zhumin Zhang、Zhuojia Xu、Xingbang Liu、Shiwei Luo、Tiehai Li
    DOI:10.1021/acs.orglett.1c02158
    日期:2021.8.6
    An efficient and simple approach for stereoselective synthesis of β-Kdo C-glycosides was described, which relies on easily available peracetylated anomeric acetate or anomeric 2-pyridyl sulfide to couple with carbonyl compounds via SmI2-mediated Reformatsky reactions. The utility of this methodology is exemplified by the streamlined synthesis of a practical β-Kdo C-glycoside with an anomeric aminopropyl
    描述了一种用于立体选择性合成 β-Kdo C-糖苷的有效且简单的方法,该方法依赖于容易获得的全乙酰化异头乙酸盐或异头 2-吡啶醚,通过 SmI 2介导的 Reformatsky 反应与羰基化合物偶联。这种方法的效用通过实用的 β-Kdo C-糖苷的流线型合成与异头基丙基接头的流线型合成来举例说明,以与其他生物分子结合以进行进一步的生物学研究。
  • Synthesis of ld-Hepp and KDO containing di- and tetrasaccharide derivatives of Neisseria meningitidis inner-core region via iodonium ion promoted glycosidations
    作者:G.J.P.H. Boons、F.L. van Delft、P.A.M. van der Klein、G.A. van der Marel、J.H. van Boom
    DOI:10.1016/s0040-4020(01)88191-6
    日期:——
    The synthesis of methyl(ethyl) 2-thio-KDO (i.e. 1, 2, 5, 7 and 10) and ethyl 1-thio-LD-Hepp (i.e. 26 and 43) derivatives will be described. The latter derivatives proved to be suitable donors in iodonium ion (NIS/IFOH) promoted glycosidation reactions. The usefulness of the glycosidation approach was illustrated by the successful conclusion of a spacer containing dimer L-alpha-D-Hepp-(1 --> 5)-alpha-KDO-2-O-(CH2)3NH2 (37) and tetramer beta-D-Galp-(1 --> 4)-beta-D-Glep-(1 --> 4)-L-alpha-D-Hepp-(1 -->5)-alpha-KDO-2-O-(CH2)3NH2 (47).
