  • Palladium(<scp>ii</scp>)-assisted activation of thioglycosides
    作者:Samira Escopy、Yashapal Singh、Alexei V. Demchenko
    DOI:10.1039/d1ob00004g
    日期:——
    Described herein is the first example of glycosidation of thioglycosides in the presence of palladium(II) bromide. While the activation with PdBr2 alone was proven feasible, higher yields and cleaner reactions were achieved when these glycosylations were performed in the presence of propargyl bromide as an additive. Preliminary mechanistic studies suggest that propargyl bromide assists the reaction
    本文描述的是在溴化钯( II )存在下硫代糖苷的糖苷化的第一个实例。虽然单独使用 PdBr 2进行活化已被证明是可行的,但当这些糖基化在炔丙基溴作为添加剂存在的情况下进行时,可以实现更高的产率和更清洁的反应。初步机理研究表明,炔丙基溴通过产生电离络合物来促进反应,从而加速离去基团的离开。研究了与不同糖基受体反应的各种硫代糖苷供体,以确定这种新反应的初始范围。还探索了硫代糖苷相对于其他离去基团的选择性和化学选择性激活。

    日期:2002.2
    A catalytic and stereoselective glycosylation of various glycosyl acceptors, such as methyl glycosides, thioglycosides, or a disarmed glycosyl fluoride, with benzyl-protected armed glycosyl fluoride was successfully carried out by using various protic acids in the presence of MS 5A. In the cases when trifluoromethanesulfonic acid (TfOH) or perchloric acid (HClO4) was used in diethyl ether (Et2O), α-glycosides
    在 MS 5A 存在下,使用各种质子酸成功地进行了各种糖基受体(如甲基糖苷、硫糖苷或脱臂糖基氟)与苄基保护的武装糖基氟的催化和立体选择性糖基化。在三氟甲磺酸 (TfOH) 或高氯酸 (HClO4) 用于乙醚 (Et2O) 的情况下,主要产物为 α-糖苷,而当四(五氟苯基)硼酸 [HB(C6F5) )4] 用于三氟甲基苯 (BTF)-新戊腈 (tBuCN) = 5:1 的混合溶剂中。这种糖基化的立体选择性受催化剂抗衡阴离子的性质以及溶剂的性质控制。还,
  • Chemoselective glycosylations using sulfonium triflate activator systems
    作者:Jeroen D.C Codée、Leendert J van den Bos、Remy E.J.N Litjens、Herman S Overkleeft、Constant A.A van Boeckel、Jacques H van Boom、Gijs A van der Marel

    日期:2004.1
    chemoselective glycosylation sequence is described that employs the recently developed BSP/Tf2O and DPS/Tf2O reagent systems to activate thioglycosides. In the first glycosylation event a relatively armed thioglycoside is activated with the BSP/Tf2O activator system and condensed with an acceptor thioglycoside to yield the thiodisaccharide, which is activated with the more potent DPS/Tf2O activator in the
    描述了一种新颖的化学选择性糖基化序列,该序列采用了最近开发的BSP / Tf 2 O和DPS / Tf 2 O试剂系统来激活硫糖苷。在第一次糖基化事件中,相对武装的硫代糖苷被BSP / Tf 2 O活化剂系统激活,并与受体硫糖苷缩合,生成硫二糖,后者在下一次糖基化事件中被更有效的DPS / Tf 2 O活化剂激活。(N-哌啶子基)苯基(S-硫代苯基)硫化物三氟甲磺酸酯的淬灭是在亚磷酸三乙酯活化后形成的,其对于亚磷酸三乙酯的生产至关重要。
  • A Catalytic and Stereoselective Glycosylation with Glucopyranosyl Fluoride by Using Various Protic Acids
    作者:Hideki Jona、Hiroki Mandai、Teruaki Mukaiyama
    DOI:10.1246/cl.2001.426
    日期:2001.5
    A catalytic and stereoselective glycosylation with glucosyl fluoride was effectively performed by using a catalytic amount of various protic acids. When the glycosylation was carried out, for example, using perchloric acid (HClO4) in diethyl ether (Et2O), the major products were α-glycosides while β-stereoselectivity was observed when tetrakis(pentafluorophenyl)boric acid [HB(C6F5)4] was used in a mixed solvent of trifluoromethylbenzene (BTF)–pivalonitrile (tBuCN) = (5:1). The stereoselectivity was controlled by not only the effect of solvent but also by the nature of counter anion of the catalyst such as B(C6F5)4− or ClO4−.
    通过使用催化量的各种原酸,可以有效地利用葡萄糖基氟化物进行催化和立体选择性糖基化。例如,在二乙醚(Et2O)中使用高氯酸(HClO4)进行糖基化时,主要产物为α-糖苷,而在三氟甲基苯(BTF)-特戊腈(tBuCN)=(5:1)混合溶剂中使用四(五氟苯基)硼酸[HB(C6F5)4]时,则观察到了β-立体选择性。立体选择性不仅受溶剂的影响,还受催化剂反阴离子(如 B(C6F5)4- 或 ClO4-)性质的控制。
  • Chemoselective glycosylations (part 1): Differences in size of anomeric leaving groups can be exploited in chemoselective glycosylations
    作者:Geert-Jan Boons、Richard Geurtsen、Duncan Holmes
    DOI:10.1016/0040-4039(95)01222-4
    日期:1995.8
    We have developed a novel chemoselective glycosylation strategy. This glycosylation strategy is based on the fact that the glycosyl reactivity of an anomeric thiol group can be control by the bulkiness of this group whereby we have produced a new range of differentially reactive coupling substrates. The new approach will enable complex oligosaccharides of biological importance to be prepared in a highly
    我们已经开发出一种新颖的化学选择性糖基化策略。该糖基化策略基于以下事实:异头硫醇基团的糖基反应性可以通过该基团的庞大来控制,由此我们生产了一系列新的差异反应性偶联底物。新方法将使具有生物学重要性的复杂寡糖能够以高度融合的方式制备。
