1. Synthesis of Orthogonally Functionalized Oligosaccharides for Self-assembled Monolayers and as Multimodal Tools in Chemical Biology
Abstract : This thesis covers different topics in the field of synthetic organic chemistry combined with the field of surface science and glycobiology.First, the text presents a series of orthogonally protected oligosaccharides (tri-, penta-, and heptasaccharides) of varying length and structures, which are synthesized with the aim of developing novel heterobifunctional biocompatible cross-linkers.

2. Synthesis of oligosaccharides and conformational analysis by NMR spectroscopy
Abstract : 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. READ MORE

3. Reaction Between Grignard reagents and Heterocyclic N-oxides : Synthesis of Substituted Pyridines, Piperidines and Piperazines
Abstract : This thesis describes the development of new synthetic methodologies for preparation of bioactive interesting compounds, e.g. substituted pyridines, piperidines or piparazines. Thesecompounds are synthesized from commercially available, cheap and easily prepared reagents, videlicet the reaction between Grignard reagents and heterocyclic N-oxides. READ MORE
