5-lactone and manno-1,5-lactone derivatives and other possible products has also been ruled out by synthesis of possible exo-glycal derivatives of these lactones using the Ramberg–Bäcklund rearrangement of the corresponding sulfones.
葡糖醛-1,5-内酯的甲硅烷基化反应可根据所采用的反应条件而给出过甲硅烷基化的葡糖醛-1,5-内酯或过甲硅烷基化的1,4-内酯。2,3,5,6-四-O-(叔丁基二甲基甲硅烷基)-d-葡萄糖基-1,4-内酯的结构,是由葡萄糖基1,5-内酯与TBSOTf和X射线晶体学证实了二氯甲烷中的二甲基吡啶。通过使用相应砜的Ramberg-Bäcklund重排合成这些内酯的可能的糖基外衍生物,还排除了葡萄糖基-1,5-内酯和甘露-1,5-内酯衍生物及其他可能产物的形成。
