A novel procedure for the synthesis of isoxazolin-5-one glycosides starting from unprotected carbohydrates is described. The substrate scope of the one-pot synthetic protocol was explored using D-configured glucose, xylose, maltose, fructose, ribose and 2-deoxyribose. Naturally occurring 2-(β-D-glucopyranosyl)-3-isoxazolin-5-one and four novel isoxazolin-5-one glycosides derived from xylose, maltose
描述了一种从未保护的碳水化合物开始合成异恶唑啉-5-酮糖苷的新方法。使用D-构型的葡萄糖,木糖,麦芽糖,果糖,核糖和2-脱氧核糖探索一锅合成方案的底物范围。合成了天然存在的2-(β- D-吡喃葡萄糖基)-3-异恶唑啉-5-酮和四种衍生自木糖,麦芽糖和果糖的新型异恶唑啉-5-酮糖苷,并通过快速色谱法纯化。根据化学结构,光物理性质以及pH稳定性对化合物进行了表征。将合成的糖苷的光水解速率与尿苷作为标准进行比较,以确定水中光反应的量子产率。
