preparations of thioglycoside derivatives of L-idose and L-iduronic acid are described. The method avoids the tedious chromatographic separations of furanose and pyranose anomeric mixtures, and affords the thioglycosides in a stereoselective manner. The L-idose and L-iduronic acid thioglycosides having combinations of different protecting groups proved to be efficient glycosyl donors in the synthesis of heparin
描述了L-异糖和L-艾杜糖醛酸的硫代糖苷衍生物的有效制剂。该方法避免了呋喃糖和吡喃糖异头混合物的繁琐色谱分离,并以立体选择性方式提供了硫糖苷。具有不同保护基的组合的L-异糖和L-艾杜糖醛酸硫糖苷被证明是肝素二糖合成中有效的糖基供体。
