    从市售甲基六吡喃糖苷分两步合成了大量(> 3 g)新系列的尿酸烷基酯。首先,使用2,2,6,6-四甲基-1-哌啶基氧基自由基(TEMPO)催化的氧化,将数十克的游离甲基α-d-吡喃葡萄糖苷选择性和定量地氧化为相应的尿酸钠。然后通过与脂肪醇(乙基至月桂醇)的酸介导的酯化作用引入不同长度的疏水链,从而以中等至良好的收率(49%-72%)得到所需的葡糖醛酸烷基酯。该方法已成功应用于甲基α-d-甘露吡喃糖苷和甲基β-d-吡喃半乳糖苷。测量了一些物理化学性质,例如临界胶束浓度(CMC),CMC处的平衡表面张力(γcmc),溶解度和Krafft温度,

    The kinetics of the TEMPO-mediated oxidation of methyl α-d-glucopyranoside to sodium methyl α-d-glucopyranosiduronate were studied. An intermediate was found which was identified as the hydrated aldehyde. This was oxidised in the same manner as the alcohol, with pseudo first order rate constants ratio kobs,ald/kobs,alc — 7. The reaction mechanism is discussed with emphasis on steric factors and compared

    (HPAEC). The optimum pH for the reaction was between 10 and 11. The oxidation was found to be first order in TEMPO and Br-. The oxidation method can be applied to determine the amount of primary alcohol groups in water-soluble glucans; for pullulan, a proportion of 70% and for dextran, a proportion of 3% primary alcohol groups was found.

  • Sucrose tricarboxylate by sonocatalysed TEMPO-mediated oxidation

    DOI:10.1016/s0008-6215(00)00046-x
    日期:2000.6
    Oxidation of sucrose by the NaOCl/TEMPO system provided sucrose tricarboxylate without the addition of sodium bromide as co-catalyst when high-frequency (500 kHz) ultrasound was applied, in contrast to very limited conversion without sonication. In the presence of sodium bromide, sonication also caused acceleration of the oxidation. The rate increase due to sonication of the oxidant system prior to sucrose addition suggests that ultrasound acts at the level of the formation of the nitrosonium ion, the active oxidising species in the catalytic cycle.
