  Sequential Removal of Monosaccharides from the Reducing End of Oligosaccharides. 2. Fundamental Studies of a Reaction between Hydrazino Compounds and Sugars Having a Glycosyl Moiety on a Carbon Atom Adjacent to a Carbonyl Group

  摘要：

  Hydrazine and certain hydrazino derivatives react with sugars having a glycosidic substituent, where the glycosyl moiety is located on a carbon atom adjacent to an aldehyde or keto group of the aglycon, resulting in cleavage of the glycosidic linkage. The reaction proceeds whether the glycon is of the alpha or beta configuration. The released glycosyl moiety, in the presence of excess hydrazino compound, reacts further to give a hydrazone derivative. Removal of the hydrazone group gives the reducing sugar derived from the glycon.
