nitrogen atoms replacing the ring and glycosidic oxygen atoms has been prepared in a single step from 5-O-mesyl-d-mannofuranose by a process that likely involves double displacement and an epoxide intermediate. A similar but protected bicyclic analogue of 6-deoxy-β-l-gulopyranose has been prepared by an electrophilic cyclization reaction.
β-d-甘露吡喃糖的双环类似物,其中氮原子取代了环和糖苷氧原子,是通过5 - O-甲磺酰基-d-甘露糖呋喃糖通过一步法制备的,该过程可能涉及两次置换和环氧化物中间体。已经通过亲电环化反应制备了类似但受保护的6-脱氧-β-1-戊吡喃糖的双环类似物。
