    New α-selective thermal glycosylation of acetyl-protected 2-acetamido-2-deoxy-β-d-glucopyranosyl diphenylphosphinate
    摘要:
    This paper describes new alpha-selective thermal glycosylation using acetyl-protected 2-acetamido-2-deoxy-beta-D-glucopyranosyl diphenylphosphinate (4) as a glycosyl donor. When the glycosylation of 4 with 1-hexanol was carried out under Various conditions, the conditions using trimethylsilyl trifluoromethanesulfonate as a promoter in nitromethane at reflux temperature were most suitable for the formation of the alpha anomer. The glycosylation of 4 with the other common alcohols gave corresponding alpha-glycosides in relatively high yields under the conditions. When cholesterol, a very steric hindered alcohol, was used as a glycosyl acceptor, alpha-glycoside was also produced predominantly. (C) 2000 Elsevier Science Ltd. All rights reserved.

    2-Methyl-(3,4,6-tri-O-acetyl-1,2-dideoxy-α-D-glucopyrano)[2,1-d]-2-oxazoline (5) was reacted with glycosyl acceptors bearing primary (6, 8, 10, 20) or secondary hydroxy groups (12, 14, 16, 18) in the presence of anhydrous cupric bromide or cupric chloride at elevated temperature to provide 2-acetamido-2-deoxy-β-D-glucopyranosides in 36−92% yield. The reaction conditions are milder than those previously

    lipo-chitin oligosaccharide signal molecules (Nod factors) that are essential for the formation of symbiotic organs on the roots of host plants, a process known as nodulation. Biosynthesis of the chitin oligosaccharide moiety in Nod factors is carried out by the rhizobial N-acetylglucosaminyltransferase NodC. The initial acceptor or primer used for the synthesis of chitin oligosaccharides in vivo is
    摘要根瘤菌细菌合成了脂-几丁质寡糖信号分子(Nod因子),这对于在宿主植物根部形成共生器官至关重要,这一过程称为结瘤。Nod因子中的几丁质寡糖部分的生物合成是通过根瘤菌N-乙酰氨基葡萄糖氨基转移酶NodC进行的。用于体内几丁质寡糖合成的初始受体或引物是未知的。为了研究NodC的受体特异性,我们合成了具有不同糖苷配基的N-乙酰氨基葡糖(GlcNAc)衍生物,并使用表达lotorhizobium loti几丁质寡糖合酶NodC的大肠杆菌菌株的膜制剂在体外测试了它们是否为NodC的受体。使用薄层色谱法分析反应产物表明,含有简单烷基链或连接C-1的其他疏水基团的GlcNAc衍生物是NodC的受体。该酶似乎对糖苷配基是β-连接的受体具有特异性。NodC仍将其中GlcNAc的N-乙酰基部分的甲基被烯丙氧基或苄氧基取代的GlcNAc衍生物用作受体。因此,在该位置上的原始甲基对于NodC和GlcNAc之间

    microwave conditions were needed to attain acceptable yields with less reactive, carbohydrate based glycosyl acceptors. The protocol developed was applied to provide the first example of direct chemical formation of a disaccharide using both GlcNAc as a glycosyl donor and acceptor. The alpha-acetate donor was found to be significantly less reactive than the corresponding beta-anomer necessitating higher
    使用过乙酰化的β-GlcNAc和β-GalNAc作为供体,开发了一种直接,温和且有效的方案,用于制备N-乙酰基氨基葡萄糖(GlcNAc)和N-乙酰基半乳糖胺(GalNAc)的β-糖苷。发现所有筛选的稀土金属三氟甲磺酸盐启动子均能促进糖基化,而Sc(OTf)(3)的反应速率则更高。发现简单的醇糖基化可在回流的二氯甲烷中顺利进行,而在微波条件下需要较高的温度才能获得可接受的收率,且反应性较低的基于碳水化合物的糖基受体。应用所开发的方案,以提供同时使用GlcNAc作为糖基供体和受体的二糖直接化学形成的第一个例子。发现α-乙酸酯供体比相应的β-端基异构体显着更低的反应性,这需要更高的反应温度,在该温度下发现发生糖苷的异构化。可以确定,仅在Sc(OTf)(3)和乙酸都存在的情况下才会发生异化反应。

    A mild and efficient method for preparation of GlcNAc derivatives by reaction of glycosyl acceptors with glycosyl oxazolines has been developed. The key feature is use of Yb(OTf)3 as promoter, requiring moderate reaction times and equivalence stoichiometry. We anticipate application in the preparation of a wide range of derivatives of this biologically important class of building blocks.
