1. Selective Transformations of Allylic Compounds and Enol Derivatives : Synthesis of Fluorinated and Nitrogenated Scaffolds
Sammanfattning : In this thesis, new synthetic methods to give access to molecules having fluorinated scaffolds and other polar functional groups have been developed. The methods give access to highly valuable organic compounds that may serve as building blocks in the synthesis of functionalized drug candidates. LÄS MER
2. Methodologies to assess the fate of polar organic compounds in aquatic environments
Sammanfattning : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

3. Synthetic studies of rigid tetracyclic oxanorbornanes. Regioselective reductive Heck arylation of a tetracyclic scaffold
Sammanfattning : Rigid or conformationally restricted compounds are intresting from a pharmacological point of view since they do not have to pay the entropy penalty paid by more flexible molecules in binding to e.g. a protein. LÄS MER
4. Naphthoxylosides Investigations into glycosaminoglycan biosynthesis
Sammanfattning : Glycosaminoglycans (GAGs) are members of a family of polysaccharide structures consisting mostly of repeating disaccharide units. Most GAGs are attached to specific serine residues in proteins to form proteoglycans (PGs). LÄS MER
5. Sample Preparation of Organic Compounds in Environmental Analysis using Liquid Membrane Extraction
Sammanfattning : This thesis demonstrates the potential of the liquid membrane extraction technique as an alternative method for the analysis of trace ionisable organic compounds in the environment. Liquid membrane based extraction methods for the analysis of s-triazine herbicides and phenolic compounds were developed. LÄS MER
