    Stereoselective Synthesis of α- and β-Glycosylamide Derivatives from Glycopyranosyl Azides via Isoxazoline Intermediates
    摘要:
    Treatment of 2-acetoxy glycopyranosyl azides with Ph3P gave isoxazolines by ring closure of the phosphorimine. Coupling of in situ generated isoxazolines with acylating reagents gave mixtures of alpha- or beta-glycopyranosyl amides. The alpha/beta ratio depended upon the acylating reagent and metal salts employed. For example, coupling of isoxazoline 3 with Z-Asp-(SPy)-OBn in the presence of CuCl2 gave exclusively alpha-N-glucopyranosylasparagine derivative 8. This general procedure has been applied to mono-, di-, and trisaccharide systems.

    Glycosyl dialkyl- and diacyl-glycerols bearing saturated, unsaturated or chiral methyl branched chains in the tail and disaccharide and trisaccharide carbohydrate headgroups were synthesised. Standard procedures were used for the preparation of the educts and the glyco lipids: trichloracetimidate procedure for the preparation of long-chained compounds, glycosylation using the beta-peracetate and boron

    An efficient cleavage-isopropylidenation reaction of sucrose, catalyzed by iodine, is described. Related D-fructofuranosyl-containing oligosaccharides, some common disaccharides and their individual monosaccharide units were treated in a similar manner to yield isopropylidenated monosaccharide derivatives. The reaction conditions are particularly mild and selective. Some mechanistic aspects of the

    Iminosugars are an important class of natural products and have been subject to extensive studies in organic synthesis, bioorganic chemistry and medicinal chemistry, yet only a limited number of these studies are on glycosylated iminosugars. Here, a general route of synthesis is presented towards glycosylated 1‐deoxynojirimycin derivatives based on the oxidation–reductive amination protocol that in

    为了商业化糖脂佐剂的生产,它们的合成既需要坚固又便宜。在本文中,我们描述了一种半合成方法,其中脂质受体源自古细菌盐沼的生物量,并且糖基供体是化学合成的。这项工作提出了一些初步的结果,使用促进剂系统N-代琥珀酰亚胺(NIS)和稳定的0.25 M三氟化硼-三氟乙醇(BF(3)x TFE(2))在二氯甲烷中的溶液。该促进剂系统允许使用过乙酰基烷基(芳基)代糖苷,其可通过促进清洁的糖基化反应从廉价的二糖起始原料中以高收率获得,从中可以容易地分离出纯产物。使用NIS三氟甲磺酸盐(AgOTf)进行常规糖基化会导致大量乙酰基转移到古菌受体和许多副产物上,使纯化变得复杂。作为初步的佐剂活性研究的一部分,我们描述了具有O-2甲酰基基团的龙胆二糖β-Glcp-(1-> 6)-Glcp-SEt供体的一锅合成以85%的总收率连接到古菌的二糖,以及相关的糖脂三糖β-Glcp-(1-> 6)-β-Glcp-(1->
