1. Synthesis of some oligosaccharides with D-galacto- and D-gluco-configuration and reductive opening of carbo-hydrate acetals
Sammanfattning : Syntheses of the following oligosaccharides, required for immunological studies. are discussed: £-trifluoroacetamidophenyl O-a-D-glucopyranosyl-(1+4)-a-D-galactopyranoside, ß-trifluoroacetamidophenyl O-a-D-glucopyranosyl-(1 + 6)-a-D-galactopyranoside, 8-methoxy- carbonyloct-1-yl 0-a-D-galactopyranosyl-(1+3)-fi-ß~9"9alact°Pyranosyl- (1+4)-2-acetamido-2-deoxy-ß-D-glucopyranoside, methyl û-a-D-fuco- pyranosyl-(1+4)-ß-D-galactopyranoside, methyl û-a-D-galactopyranosyl- (1+4)-ß-D-fucopyranoside and methyl ß-a-D-fucopyranosyl-(1+4)-ß-D- fucopyranoside.

2. Synthesis of Oligosaccharides for Interaction Studies with Various Lectins
Sammanfattning : In this thesis, the syntheses of oligosaccharides for interaction studies with various lectins are described. The first section reports the syntheses of tetra, tri- and disaccharides corresponding to truncated versions of the glucosylated arm of Glc1Man9(GlcNAc)2, found in the biosynthesis of N-glycans.

3. Design and Synthesis of Sialic Acid Conjugates as Inhibitors of EKC-causing Adenoviruses
Sammanfattning : The combat against viral diseases has been, and still is, a major challenge in the field of drug development. Viruses are intracellular parasites that use the host cell ma-chinery for their replication and release. Therefore it is difficult to target and destroy the viral particle without disturbing the essential functions of the host cell. LÄS MER

5. Synthesis of Oligosaccharides from the Inner Core Structure of Haemophilus Influenzae and Neisseria meningitidis Lipopolysaccharides
Sammanfattning : This thesis describes the synthesis of oligosaccharides corresponding to different parts of the lipopolysaccharide (LPS) inner core structure from Haemophilus influenzae and Neisseria meningitidis. Chapter 2 describes the synthesis of a protected trisaccharide common to H. influenzae and N. LÄS MER
