Using 3-O-benzoyl-4,6-O-di-tert-butylsilylidene-2-azido-2-deoxy-selenogalactoside, biotinylated oligo-α-(1→4)-D-galactosamines comprising from 2 to 6 GalN units were prepared for the first time together with their N-acetylated derivatives. The combination of blocking groups used herein pr...
To address this, density functional theory (DFT) methods have been used to calculate vicinal coupling constants inN-acetylated amino sugars and derive empirical Karplus equations for3J(HNH2)ofN-acetyl-d-glucosamine (GlcNAc) andN-acetyl-d-galactosamine (GalNAc). The fitted Karplus parameters were ...
