described. The L-iduronyl and D-glucuronyl disaccharides 1−3 were then prepared from these compounds, by means of efficient and regioselective protective group manipulations. These disaccharides form the basis of a combinatorial approach toward the synthesis of heparan sulfate fragments representative of the heterogeneous regions of this polysaccharide.

描述了获得适当保护的 L-艾杜糖醛酸单糖供体 4 和 5 以及 2-叠氮葡萄糖受体 6 和 7 的新的多克路线。然后通过有效和区域选择性的保护基操作,从这些化合物制备 L-艾杜糖醛酸和 D-葡萄糖醛酸二糖 1-3。这些二糖构成了合成代表这种多糖异质区域的硫酸乙酰肝素片段的组合方法的基础。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
