1. On the Versatility of Microwave-Assisted Chemistry : Exemplified by Applications in Medicinal Chemistry, Heterocyclic Chemistry and Biochemistry
Sammanfattning : Today, the demand for speed in drug discovery is constantly increasing, particularly in the iterative processes of hit validation and expansion and lead optimization. Irradiation with microwaves (MWs) has been applied in the area of organic synthesis to accelerate chemical reactions and to facilitate the generation of new chemical entities since 1986. LÄS MER
2. Silaborations of Unsaturated Compounds
Sammanfattning : This thesis deals with the development of transition metal-catalyzed silaborations of 1,3-dienes and 1,6-enynes. The first part of the thesis describes the development of the enantioselective 1,4-silaboration of 1,3-cyclohexadiene. A number of chiral metal-ligand complexes were evaluated. LÄS MER
3. Chemo-Enzymatic Epoxidation of Unsaturated Fatty Acids
Sammanfattning : Epoxy fatty acids are useful molecules and find a number of applications e.g. as PVC plasticisers and stabilisers, additives in polyurethane production, reactive diluents in paints, corrosion protection agents, etc. LÄS MER
4. Transport and Fate of Escherichia coli in Unsaturated Porous Media
Sammanfattning : The unsaturated zone could provide an effective barrier against pathogenic microbes entering the groundwater. Knowledge relating to microbial fate in this zone is therefore important for increased understanding of groundwater vulnerability. LÄS MER
5. Unsaturated Solute Transport in a Semiarid Catchment - Nonlinear Analyses and Modelling
Sammanfattning : Unsaturated solute transport is highly variable and therefore difficult to predict. In semi-arid areas, where water resources are limited, the presence of macropores is of great importance for crop production. The bromide ion (Br-) and dye tracers are useful for studies of water movement. LÄS MER
