    Isopropenyl glycosides and congeners as novel classes of glycosyl donors: theme and variations
    摘要:
    Isopropenyl glycosides (i.e., 10 and 11) have been synthesized in high yields by reacting the corresponding anomeric acetates with the Tebbe reagent. These compounds undergo glycosylation with primary or secondary carbohydrate alcohols in the presence of trimethylsilyl triflate or boron trifluoride etherate, probably via a mixed acetal glycoside intermediate. On the basis of this principle, a quite efficient glycosylation of monosaccharide hemiacetal donors (i.e., 1, 7, and 9) with acceptors bearing an isopropenyl ether function at a primary or secondary position (i.e., 18 and 21) has been developed. Also investigated were the glycosylating properties of isopropenyl glucosyl and galactosyl carbonates (i.e., 12-15), easily prepared from the corresponding hemiacetals, toward sugar alcohols. In each case, the beta-selective synthesis of disaccharides from donors having nonparticipating groups at C-2 was ensured by the use of acetonitrile, at low temperature, as the solvent.

    糖基碘化物在中性条件下是高效的供体
    摘要:
    摘要制备了糖基碘化物并在中性条件下进行糖基化。该反应是高效的,即使具有空间上要求的糖基受体也能得到α糖苷。葡萄糖基碘与烯丙醇的反应最慢,需要回流条件。半乳糖基碘化物是反应性的中间产物,在室温下3小时内可提供烯丙基糖苷,而岩藻糖基碘化物的糖基化在相似条件下可在不到1小时内发生。用包括异头羟基在内的各种受体证明了反应的范围和局限性,得到了海藻糖类似物。在不存在C-2参与的情况下,只需将溶剂从苯改成乙腈就可以实现葡萄糖基碘化物的β-选择性糖基化。

    The glycosylation of O-glycosyl trichloroacetimidate donors using a synergistic catalytic system of electron-deficient pyridinium salts/aryl thiourea derivatives at room temperature is demonstrated. The acidity of the adduct formed by the 1,2-addition of alcohol to the electron-deficient pyridinium salt is increased in the presence of an aryl thiourea derivative as an hydrogen-bonding cocatalyst. This
    证明了在室温下使用缺电子的吡啶鎓盐/芳基硫脲衍生物的协同催化系统对O-糖基三氯乙酰基亚氨酸酯供体的糖基化作用。在芳基硫脲衍生物作为氢键合助催化剂的存在下,由醇向缺电子的吡啶鎓盐的1,2-加成形成的加合物的酸度增加。这种转化在温和的反应条件下进行,反应条件与各种O-糖基三氯乙酰亚氨酸酯供体和糖基受体结合,以中等到良好的产率提供了可预测的选择性的相应O-糖苷。另外,通过使用部分保护的受体,优化的方法也用于区域选择性的O-糖基化。

Good anomeric selectivity was observed for the Ferrier rearrangements, whereas the O-glycosylation

    Adduct formation between alcohols as glycosyl acceptors and phenylsilicon trifluoride (PhSiF3) as catalyst permits acid‐base‐atalyzed glycosidations with O‐glycosyl trichloroacetimidates as glycosyl donors. In this way, from various glycosyl donors and acceptors 1,2‐trans‐ and some 1,2‐cis‐glycosides could be obtained with high anomeric selectivity. A preference for an intramolecular bimolecular nucleophilic

    p-cyano-o-methoxybenzoate donors. In glycosylation reactions with o-methoxybenzoate donors, the yields of disaccharide products were good to excellent for various glycosyl acceptors, including a carbohydrate-based secondary alcohol. Furthermore, β-selective mannosylation was achieved with a Crich-type donor at 0 °C to ambient temperature, without donor preactivation. The donor was also used for the first
    我们将 β-邻甲氧基苯甲酸酯描述为一种用于催化化学糖基化的储存稳定且实用的 C-1 核离心剂,其中苯甲酸副产物可以很容易地去除、重新分离,并可能在糖基化反应后回收。这种新型糖基供体可以通过一系列促进剂有效活化,包括 Bi(OTf)3、Fe(OTf)3、TMSOTf(TMS = 三甲基甲硅烷基)和三氟甲磺酸,催化剂用量低(<10 mol-%)负荷。供体显示出比类似的苯甲酸盐、对甲氧基苯甲酸盐和对氰基-邻甲氧基苯甲酸盐供体更高的反应性。在与邻甲氧基苯甲酸酯供体的糖基化反应中,对于各种糖基受体(包括基于碳水化合物的仲醇),二糖产物的产率从好到极好。此外,β-选择性甘露糖基化是用 Crich 型供体在 0°C 至环境温度下实现的,无需供体预活化。供体也用于一锅两步糖基化的第一步,得到三糖;第二个偶联涉及用 NIS/TMSOTf(NIS = N-碘代琥珀酰亚胺)激活硫糖苷。我们相信这为当前协议提供了一个很好的替代方案。

    A straightforward method utilizing a bismuth(V) compound was developed for the activation of thiopropylglycosides for coupling to various acceptors; good to excellent yields were obtained without applying additional additives/co‐promoters.
