The title synthesis is described by 1,2-addition of 20mercaptpyridine (1) on simple (2 and 3) as well as on sensitive glycal saccharides (7 and 8) to obtain the respective 2-deoxy 2-pyridyl 1-thioglycopyranosyl donors (4, 5, 9, 10). Glycosylations by the proven methyl iodide activation procedure is described.
标题合成由1,2-加成20mercaptpyridine(描述1上简单()2和3),以及对敏感烯糖的糖类(7和8),以获得相应的2-脱氧-2-吡啶基-1- thioglycopyranosyl供体(4、5、9、10)。描述了通过公认的甲基碘活化程序进行的糖基化。
