TLDR
For non-anomeric CH bonds, the 1JC,He values are 4-9 Hz larger than the 1 JC,Ha values as discussed by the authors, which is a significant difference.About:

Journal ArticleDOI
Glycopeptide synthesis and the effects of glycosylation on protein structure and activity.
TL;DR: It is demonstrated that with the help of synthetic glycopeptides the effects of glycosylation on protein structure and function can be studied in molecular detail.
Journal ArticleDOI
One-step conversion of unprotected sugars to β-glycosyl azides using 2-chloroimidazolinium salt in aqueous solution
TL;DR: Various beta-glycosyl azides have been synthesized directly in water by the reaction of unprotected sugars and sodium azide mediated by 2-chloro-1,3-dimethylimidazolinium chloride (DMC).

Carbon-proton coupling constants in the conformational analysis of sugar molecules.
Igor Tvaroška,F. R. Taravel +1 more
TL;DR: This chapter examines the carbon–proton coupling constants involved in the conformational analysis of sugar molecules and it is found that two-bond carbon– Proton Coupling constants are much smaller than one-bonding couplings and their signs can be negative or positive.
Journal ArticleDOI
Synthesis, Structure and Reactions of Glycosyl Azides
TL;DR: A review on these synthetically useful intermediates was published by Micheel and Klemer as mentioned in this paper more than 30 years ago but newer treatments scarcely take notice of these compounds despite their definite importance as precursors to glycosyl amines and heterocyclic derivatives such as 1,2,3-triazoles.

The azidonitration of tri-O-acetyl-D-galactal
R. U. Lemieux,R. M. Ratcliffe +1 more
TL;DR: In this article, a reaction of 3,4,6,tri-O-acetyl-D-galactal with excess ammonium nitrate and sodium azide in acetonitrile produced 2-azido-1-nitrate addition products (53% β-Galacto, 22% α-GalACTo, and 8% α -Ta...

Broadband homonuclear decoupling in heteronuclear shift correlation NMR spectroscopy
TL;DR: In this article, the authors proposed an approach to homonuclear broadband decoupling for semiselective heteronuclear J spectroscopy, where all protons which are not directly attached to a 13C nucleus experience an effect as if a nonselective 180" pulse were applied, while protons bonded to a r3C nucleus are not affected.
