  • Synthesis of blood group A and B (type 2) tetrasaccharides. A strategy with fucosylation at the last stage
    作者:Roman A. Kunetskiy、Galina V. Pazynina、Igor A. Ivanov、Nicolai V. Bovin

    The traditionally used strategy for the synthesis of blood group A and B tetrasaccharides includes 2'-O-fucosylation of lactosamine followed by insertion of an α1-3 linked N-acetylgalactosamine or a galactose moiety. Here, we report the synthesis of 3-aminopropyl glycosides of A (type 2) and B (type 2) tetrasaccharides via an alternative sequence, i.e. α-galactosaminylation (or α-galactosylation) followed
    传统上用于合成血型 A 和 B 四糖的策略包括乳糖胺的 2'-O-岩藻糖基化,然后插入 α1-3 连接的 N-乙酰半乳糖胺或半乳糖部分。在这里,我们报告了通过替代序列合成 A(2 型)和 B(2 型)四糖的 3-基丙基糖苷,即 α-半乳糖胺化(或 α-半乳糖基化),然后是 α-岩藻糖基化。该策略使我们能够合成不含岩藻糖的三糖 GalNAcα1-3Galβ1-4GlcNAc 和 Galα1-3Galβ1-4GlcNAc,它们是利用针对三糖的人类天然抗体进行免疫治疗的有前景的靶标。该方案的关键阶段是在具有第二个 (3-OH) 未保护基团的中间体三糖中对 βGal 的 2'-OH 基团进行选择性乙酰化。
  • Block synthesis of A (type 2) and B (type 2) tetrasaccharides related to the human ABO blood group system

    Herein we report the synthesis of 3-aminopropyl glycosides of A (type 2) and B (type 2) tetrasaccharides via [3 + 1] block scheme. Peracetylated trichloroacetimidates of A and B trisaccharides were used as glycosyl donors. The well-known low reactivity of 4-OH group of N-acetyl-d-glucosamine forced us to test four glucosamine derivatives (3-Bz-1,6-anhydro-GlcNAc and 3-trifluoroacetamidopropyl β-glycosides
    在本文中,我们通过[3 +1]嵌段方案报告了A(2型)和B(2型)四糖的3-基丙基糖苷的合成。A和B三糖的全乙酰化三乙酰亚酸酯用作糖基供体。N-乙酰基-d-葡糖胺的4-OH基团众所周知的低反应性迫使我们测试四种葡糖胺生物(3-Ac-的3-Bz-1,6-anhydro-GlcNAc和3-三氟乙酰基丙基β-糖苷6-Bn-GlcNAc,3-Ac-6-Bn-GlcNc3和3-Ac-6-Bn-GlcNAc2)来选择用于合成2型四糖的最佳糖基受体。当3-Ac-6-Bn-GlcNAcβ的3-三氟乙酰基丙基糖苷被糖基化时,没有分离出所需的四肽。3-Bz-1,6-脱-GlcNAc衍生物的糖基化产生α-糖苷作为主要产物。只有将3-三氟乙酰基丙基3-Ac-6-Bn-GlcNAc2β用作糖基受体(β/α5:1),而与A的三乙酰亚酸酯进行糖基化反应时,只有在B(2型)四糖的合成中才能实现高立体特异性。三糖不是立体定向的(β/α1
  • Synthesis of histo blood-group antigens A and B (type 2), xenoantigen Galα1-3Galβ1-4GlcNAc and related type 2 backbone oligosaccharides as haptens in spacered form

    DOI:10.1070/mc2002v012n04abeh001591
    日期:2002.1
    The partial alpha-fucosylation of spacered (sp = CH2CH2CH2NH2) N-acetyl beta-lactosamine derivative having free hydroxy groups at C-3 and C-2' gives rise to oligosaccharides H (type 2), Le(x) and Le(y), the first one was further elongated giving rise to A (type 2) or B (type 2) tetrasaccharides; spacered trisaccharides Galalpha1-3Galbeta1-4GlcNAc and Galalpha1-4Galbeta1-4GlcNAc were synthesised by the partial alpha-galactosylation of N-acetyl beta-lactosamine derivative, having free hydroxy groups at C-4' and C-3'.
