Synthesis of novel di- and trisaccharides using enzymatic glycosylation, Dess–Martin oxidation and reductive amination allows rapid access to the target structures. Thus, a novel class of glycomimetics was obtained having nitrogen inserted as bridging atom between two non-anomeric positions. Novel di- and trisaccharide mimetics were designed using N-acetylglucosamine as a basis structure. A third monosaccharide
使用酶促糖基化、Dess-Martin 氧化和还原胺化合成新型二糖和三糖可以快速获得目标结构。因此,获得了一类新的糖模拟物,其中插入了氮作为两个非异头位置之间的桥接原子。使用 N-乙酰氨基葡萄糖作为基础结构设计了新型二糖和三糖模拟物。第三个单糖单元通过非天然的糖 - 糖键连接,没有异头中心的参与。它们的合成通过氧化、糖基化和还原胺化进行,只需要几个步骤,因此可以快速获得目标结构。通过 Dess-Martin 氧化和随后的还原胺化实现了新型假双糖的生成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany,
