1. 1. Synthesis of oligosaccharides and conformational analysis by NMR spectroscopy

   Författare :Jerk Rönnols; Göran Widmalm; Eszter Borbas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

   Sammanfattning : The first part of this thesis describes investigations of the conformations of six N-linked pseudodisaccharides (Paper I), which were synthesized as glycosidase inhibitor candidates, and 10 β-D-xylopyranoside derivatives bearing hydrophobic aglycons (Paper II), by NMR spectroscopic methods. In paper I the ring conformations of 2- and 3-amino-α-D-altropyranosides, and ω torsions of altrosides, glucosides and mannosides were described, in neutral and protonated states. LÄS MER

3. 2. Structure, dynamics and reactivity of carbohydrates : NMR spectroscopic studies

   Författare :Jerk Rönnols; Göran Widmalm; Mikael Bols; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Conformation; NMR spectroscopy; Hydrogen bond; organisk kemi; Organic Chemistry;

   Sammanfattning : The main focus of this thesis is on the ring conformations of carbohydrate molecules; how the conformational equilibria and the rates of the associated interconversions are affected by the molecular constitution and their surroundings.The conformational equilibria of a group of amine linked pseudodisaccharides, designed as potential glycosidase inhibitors, comprising α-D-altrosides are described in Chapter 3.
