Hydrazine reacts smoothly with sugars having a glycosidic substituent when the glycosyl moiety is located on a carbon atom adjacent to an aldehyde or keto group, resulting in cleavage of the glycosidic linkage. In excess hydrazine, the released glycoside forms a hydrazone from which the reducing sugar may be recovered in high yields.
当糖基部分位于与醛或酮基相邻的碳原子上时,肼与具有糖苷取代基的糖平稳地反应,导致糖苷键的断裂。在过量的肼中,释放的糖苷形成a,可以以高收率从中回收还原糖。
