    摘要:
    当乙酰化的吡喃糖1,2-(乙基邻酸酯)在酸性溶剂中水解时,邻酸酯环的开环受吡喃糖C-4位点的轴向或赤道OAc基团的影响;在酸催化水解过程中,具有C-4轴向OAc基团的3,4,6-三-O-乙酰-α-D-半乳糖吡喃糖-(8)和甲基3,4-二-O-乙酰-α-D-半乳糖酸吡喃糖-1,2-(乙基邻酸酯)(16)分别生成1,3,4,6-四-O-乙酰-α-D-半乳糖吡喃糖(9)和甲基1,3,4-三-O-乙酰-α-D-半乳糖酸吡喃糖(23),而具有C-4赤道OAc基团的3,4,6-三-O-乙酰-α-D-葡萄糖吡喃糖-(10)和甲基3,4-二-O-乙酰-α-D-葡萄糖醛酸吡喃糖-1,2-(乙基邻酸酯)(22)则分别生成2,3,4,6-四-O-乙酰-D-葡萄糖吡喃糖(11)和甲基2,3,4-三-O-乙酰-D-葡萄糖醛酸吡喃糖(24)。在酸催化水解过程中,具有C-4轴向OAc基团的3,4-二-O-乙酰-β-L-阿拉伯糖吡喃糖-1,2-(乙基邻酸酯)(34)生成1,3,4-三-O-乙酰-β-L-(35)和2,3,4-三-O-乙酰-L-阿拉伯糖吡喃糖(36)的混合物。这些1,2-(邻酸酯)的开环选择性被认为是由1,2-(邻酸)中间体的构象差异以及吡喃糖环上C-4位置的乙酰基团的取向所导致的。

  • Application of stabilized sugar-derived phosphoranes in the synthesis of higher carbon monosaccharides. First synthesis of a C21-dialdose
    作者:Slawomir Jarosz、Piotr Salanski、Mateusz Mach
    DOI:10.1016/s0040-4020(98)00021-0
    日期:1998.3
    aldehyde 1 with C9 stabilized phosphoranes 2 and 3 respectively. The “smaller” C19 sugar 13 was prepared from a C12 aldehyde 1 and C7 phosphorane 4. All reactions with phosphoranes were performed under high pressure (13 kbar). No reaction was observed under normal pressure even at high temperature (ca 140°C). The synthesis of C19 and C21 monosaccharides was accomplished also under normal pressure when phosphoranes
    C 21单糖前体11和12分别通过C 12醛1与C 9稳定的膦烷2和3的偶联而合成。在“较小” C 19糖13是从C中制备12醛1和C 7正膦4。与烷的所有反应均在高压(13 kbar)下进行。即使在高温(约140℃)下,在常压下也未观察到反应。C 19和C的合成当烷被更多的亲核性膦酸酯替代时,在常压下也可以完成21种单糖。然而,与高级糖烯酮11、12和13一起分离出部分消除的产物(M-苄醇)。糖α-羟基醛(14)即使在13kbar的压力下也不会与C 9-膦烷反应,尽管与更短的类似物-C 7烷15的反应是在常压下在沸腾的苯中进行的。
  • Convenient One-Pot Conversion of Alcohols into Esters via Hemiacetal Intermediates
    作者:Frieder W. Lichtenthaler、Pan Jarglis、Klaus Lorenz
    DOI:10.1055/s-1988-27708
    日期:——
    A simple and efficient one-pot oxidative procedure, adaptable to a large scale, is described for the preparation of methyl esters from either primary alcohols or vic-diols. The aldehyde is generated by Swern or periodate oxidation, followed by bromine oxidation of the methyl hemiacetal formed in aqueous methanolic solution.
    本文介绍了一种简单高效的氧化反应步骤,适用于大规模生产,用于从伯醇或邻二醇制备甲酯。该反应通过Swern或过碘酸氧化生成醛,然后在水合甲醇溶液中形成的甲缩醛进行氧化反应。
  • TPAP-Catalyzed Direct Oxidation of Primary Alcohols to Carboxylic Acids through Stabilized Aldehyde Hydrates
    作者:Andrea-Katharina C. Schmidt、Christian B. W. Stark
    DOI:10.1021/ol2014335
    日期:2011.8.19
    We present a simple, mild, and highly effective method for the direct conversion of primary alcohols to carboxylic acids. TPAP serves as the catalyst, and NMO·H2O plays a dual role, acting as the co-oxidant and as a reagent for aldehyde hydrate stabilization. This previously unknown stabilizing effect of geminal diols by N-oxides is the key for the efficiency of the overall transformation.
    我们提出了一种简单,温和且高效的方法,用于将伯醇直接转化为羧酸TPAP充当催化剂,NMO·H 2 O扮演双重角色,充当助氧化剂和醛合物稳定剂。N氧化物对双生二醇的这种先前未知的稳定作用是整体转化效率的关键。

  • Reinvestigation of the Thiazole Synthesis with Ethyl 3-Amino-2- [5-aryl-1,3,4-oxadiazol-2(3H)-ylidene]-3-thioxopropanoates and Related Reactions

    Treatment of the 1,3,4-oxadiazoles 3a and 3b with 3-chloropentane-2,4-dione gave the thiazoles 4a and 4b, respectively, which were methylated to furnish compounds 5a and 5b. The formation of 1,3,4-oxadiazoles using the 1,3-dithietane 1 as starting material, and the consecutive reactions mentioned above were transferred into sugar chemistry to provide the corresponding derivatives 6 - 9 in good yields. The reaction of 5a with benzyl amine, ethylene diamine and o-phenylene diamine afforded compounds 10, 11, and 12, respectively, which possess better stabilized push-pull systems than 5a. The structures of 3a, 4a, 5a, 10, 11, and 12 were compared with the previously proposed structures I - VI, respectively. The structures of compounds 1, 3b, and 11 were confirmed by X-ray diffraction studies.

    1,3,4-噁二唑3a和3b分别与3-戊二酮反应生成噻唑4a和4b,随后进行甲基化反应得到化合物5a和5b。利用1,3-二环戊烷1为起始物质进行1,3,4-噁二唑的合成,并进行上述连续反应,成功地将其转化为糖化学中的相应衍生物6-9,收率良好。化合物5a与苄胺乙二胺邻苯二胺反应,分别得到化合物10、11和12,它们的推-拉电子效应更稳定。化合物3a、4a、5a、10、11和12的结构分别与之前提出的结构I-VI进行了比较。化合物1、3b和11的结构经过X射线衍射研究得到了确认。
