  • Towards α- or β-d-C-glycosyl compounds by tin-catalyzed addition of glycosyl radicals to acrylonitrile and vinylphosphonate, and flexible reduction of tetra-O-acetyl-α-d-glucopyranosyl bromide with cyanoborohydride
    作者:Jean-Pierre Praly、Azin Salek Ardakani、Isabelle Bruyère、Chrystelle Marie-Luce、Bing Bing Qin

    These conditions led to 2-(α- d -manno-, and galactopyranosyl)-ethylphosphonates in 68 and 76% yields. Similarly, radical addition of acetylated 1-bromo-β- d -glucopyranosyl chloride ( 2 ) to acrylonitrile or diethyl vinylphosphonate afforded mainly intermediate chlorides which, upon radical reduction with excess tri- n -butyltin hydride, afforded the corresponding β anomers (40 and 38%, respectively)
    摘要在催化量的化三正丁基锡和过量的氰基硼氢化钠(或四正丁基)存在下,将乙酰化的α-d-葡萄糖化物(1)光诱导自由基加成到丙烯腈乙烯基膦酸乙酯中,可以高效制备α-构型的壬腈和2-(α-d-葡萄糖基)-乙基膦酸酯(产率分别为79%和70%)。这些条件导致产率为68%和76%的2-(α-d-甘露糖基和喃并喃糖基)-乙基膦酸酯。类似地,将乙酰化的1--β-d-葡萄糖(2)自由基加成到丙烯腈乙烯基膦酸乙酯中,主要得到中间体化物,在用过量的三正丁基锡氢化物进行自由基还原后,得到相应的β异构体(40和分别由38%的CC和CH键形成。立体控制依赖于d -glycopyranos-1-yl自由基的α-立体选择性猝灭。我们还发现,在叔丁醇中用过量的NaBH 3 CN进行1的紫外光辐照,可得到1,3,4,6-四-O-乙酰基-2-脱氧-α-d-阿拉伯糖-己喃糖(结晶后占65%
  • Non-isosteric C-glycosyl analogues of natural nucleotide diphosphate sugars as glycosyltransferase inhibitors
    作者:Sébastien Vidal、Isabelle Bruyère、Annie Malleron、Claudine Augé、Jean-Pierre Praly
    DOI:10.1016/j.bmc.2006.06.057
    日期:2006.11
    A series of C-glycosyl ethylphosphonophosphate analogues of UDP-Glc, UDP-Gal, UDP-GlcNAc and GDP-Fuc were synthesized from the corresponding C-glycosyl ethylphosphonic acids. Analogues were obtained as alpha-anomers through either diastereoselective photo-induced radical addition of glycosyl bromides (D-Glc, D-Gal and L-Fuc) to diethyl vinylphosphonate, or a multi-step sequence (D-GlcNAc), with subsequent coupling with morpholidate-activated nucleotide monophosphates. The in vitro inhibitory activity of UDP-Gal, GDP-Fuc and UDP-GlcNAc analogues towards glycosyltransferases (beta-1,4-Gaff, FUT3 and LgtA) was evaluated through a competition fluorescence assay and IC50 values of 40 mu M, 2 mM and 3.5 mM were obtained, respectively.

  • Diastereoselective synthesis of C-glycosylphosphonates via free-radical glycosylation
    作者:Hans-Dieter Junker、Wolf-Dieter Fessner
    DOI:10.1016/s0040-4039(97)10498-1
    日期:1998.1
    A single step approach for the diastereoselective synthesis of C-glycosidic sugar phosphonates was developed by utilizing a free radical coupling to dialkyl vinylphosphonates to give the title compounds in moderate yield. The method is broadly applicable to sugars, deoxysugars, aminosugars, and oligosaccharides. (C) 1997 Elsevier Science Ltd. All rights reserved.
