  摘要：

  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。

  NMR assignments for glucosylated and galactosylated N-acetylhexosaminitols: oligosaccharide alditols related to O-linked glycans from the protozoan parasite Trypanosoma cruzi

  摘要：

  We report full H-1 and C-13 NMR assignments for 13 gluco- or galacto-pyranosylated derivatives of GlcNAc-ol, GalNAc-ol or ManNAc-ol, many of which have been prepared by enzymatic methods. These spectra are reference data to aid the structural analysis by NMR spectroscopy of glycosylated alditols derived from the mucin of the protozoan parasite Trypanosoma cruzi. A series of structural reporter groups for the derivatives from this unusual series of O-glycans are described. (C) 2000 Elsevier Science Ltd. All rights reserved.

• 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

  日期：1995.12

  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.
