  different building blocks have been synthesised and used for the synthesis of linear triazole linked pseudo oligosaccharides with copper(I)-catalysed cycloaddition (CuAAC). Ethynylferrocene has been used as analytical probe to improve the UV/Vis properties and HPLC methods have been used and optimised for the analysis of the pseudo oligosaccharides. The smallest ones have been isolated and characterised by

  A series of eight 3, 3-disubstituted nitrosoureas (IVa-h) having the nitrosoureido group at the C-6 position of methyl glucopyranoside or methyl 2-acetamido-2-deoxy-glucopyranoside was prepared and tested for antitumor activities. Heating of the 6-O-p-tolylsulfonyl derivatives (I and II) with various alkylamines followed by reaction with 2-chloroethyl isocyanate gave the corresponding ureas (IIIa-h), which were nitrosated with nitrogen tetroxide to give IVa-h in high yields. The nitrosoureas (IVa-h) were significantly less active than the other positional isomers with respect to the nitrosoureido group prepared previously. Compounds IVa-h appear to be activated by a γ hydroxyl group at the C-4 position. The rate of activation, however, proved to be much slower than those of the C-1 or C-3 positional isomers having a β hydroxyl group. The structure-activity relationships of the positional isomers are discussed in the light of this difference in the rate of activation.

  一系列八种3, 3-二取代的亚硝基脲化合物（IVa-h）被合成，并在甲基葡萄糖吡喃糖或甲基2-乙酰氨基-2-脱氧葡萄糖吡喃糖的C-6位点上具有亚硝基脲基团，随后进行抗肿瘤活性测试。将6-O-对甲苯磺酰基衍生物（I和II）与各种烷基胺加热反应，随后与2-氯乙基异氰酸酯反应，得到了相应的脲（IIIa-h），这些脲与四氧化二氮进行亚硝化反应，得到IVa-h，产率很高。与之前合成的其他位置异构体相比，亚硝基脲（IVa-h）的活性明显较低。IVa-h化合物似乎通过C-4位置的γ羟基团被激活。然而，激活速度证明明显慢于具有β羟基团的C-1或C-3位置异构体。根据这一激活速率的差异，讨论了位置异构体的结构-活性关系。
• Triazole Linked <i>N</i>-Acetylglucosamine Based Gelators for Crude Oil Separation and Dye Removal

  Recently, phase selective organo-gelators emerged as potential materials for removal of oil from water through selective gelation. Herein, we report synthesis of a series of C-6 triazole linked N-acetylglucosamine derivatives, among which three have shown excellent selective gelation of organic solvents, diesel, petrol, and crude oils in water and seawater. We have studied phase selective gelation against

  海洋溢油对环境具有长期影响；因此，寻找补救的解决方案是科学界的主要关注。近来，相选择有机胶凝剂作为通过选择性胶凝从水中除去油的潜在材料而出现。本文中，我们报道了一系列C-6三唑连接的N-乙酰氨基葡糖衍生物的合成，其中三个在水和海水中显示出优异的有机溶剂，柴油，汽油和原油的选择性凝胶化效果。我们已经研究了针对不同API级原油（从轻到重）的相选择性凝胶化，并且在室温下使用无毒载体溶剂在不到15分钟的时间内实现了凝胶化，发现凝胶剂可用于回收原油。发现原油胶凝剂的临界胶凝浓度（CGC）为2。3-12％（w / v）。可变温度NMR和FTIR实验表明，分子间氢键是凝胶形成的原因。此外，使用胶凝剂从水中选择性去除染料。
• Synthesis of methyl 2-acetamido-2,6-dideoxy-α- and β-d-xylo-hexopyranosid-4-ulose, a keto sugar which misled the analytical chemists
  作者：Sabine Borowski、Dirk Michalik、Helmut Reinke、Christian Vogel、Anna Hanuszkiewicz、Katarzyna A. Duda、Otto Holst

  To understand the contradictory results on the structure of the lipopolysaccharide isolated from a Yersinia enterocolitica O:3, both anomers of methyl 2-acetamido-2,6-dideoxy-D-xylo-hexopyranosid-4-ulose were prepared. The key steps of the synthetic pathway were the selective acetylation of the methyl 2-acetamido-2,6-dideoxy-alpha,beta-D-glucopyranosides, the oxidation of the 4-position to form the keto-sugars, and deacetylation to provide the target compound. Surprisingly, the last step was accompanied by a disproportionation to give methyl 2-acetamido-2,6-dideoxy-alpha- and beta-D-glucopyranosides and N-(5-hydroxy-6-methyl-4-oxo-4H-pyran-3-yl)acetamide as side-products.
