has been synthesised from d-mannose by a route involving as the key step dimerisation of mannopyranosyl nitrile oxide 2. Three methods were used for the generation of the nitrile oxide: isocyanate-mediated dehydration of nitromethylmannose derivative 4, treatment of aldoxime 5 with aq. hypochlorite, and base-induced dehydrochlorination of hydroximoyl chloride 6. d-Gluco, d-galacto, d-xylo, and l-fucopyranosyl
3,4-二(2,3,4,6-四-O-乙酰基-β-d-甘露吡喃糖基)-1,2,5-恶二唑2-氧化物(7)是通过以下方法由d-甘露糖合成的作为关键步骤涉及甘露吡喃糖基一氧化氮2的二聚。三种方法用于生成一氧化氮:异氰酸酯介导的硝基甲基甘露糖衍生物4脱水,用盐酸水溶液处理醛肟5。次氯酸盐,和碱诱导的羟肟酰氯6的脱氯化氢作用。d-葡糖,d半乳糖,d-木糖和L- fucopyranosyl类似物8 - 11类似地制备。d-甘露糖衍生的1,2,5-恶二唑2-氧化物7的结构 通过X射线晶体学确定。
