1. C2- and C3-symmetric ligands via ring-opening of aziridines
Sammanfattning : This thesis deals with the design and synthesis of chiralenantiopure nitrogencontaining ligands and the use of theseligands in asymmetric catalysis. A modular synthetic approachto enantiopure nitrogen-containing ligands was developed. Thesynthetic method is based on the ring-opening of activatedchiral aziridines by nitrogen nucleophiles. LÄS MER
2. Isolation, Synthesis and Structure-Activity Relationships of Antifeedants against the Pine Weevil, Hylobius Abietis
Sammanfattning : The large pine weevil, Hylobius abietis L., is a major insect pest on conifer seedlings in northern Europe. Due to its feeding newly planted trees get girdled, resulting in high seedling mortality (up to 80%). As a consequence great financial losses to the forest industry occur. LÄS MER
3. Efficient Synthesis and Analysis of Chiral Cyanohydrins
Sammanfattning : This thesis deals with the development of new methods for efficient synthesis and analysis in asymmetric catalysis. It focuses on the preparation of chiral cyanohydrins by enantioselective addition of cyanide to prochiral aldehydes. LÄS MER
4. Contact allergens in p-tert-butylphenol-formaldehyde resin
Sammanfattning : p-tert-Butylphenol-formaldehyde resin (PTBP-F-R) is used as a binder in many adhesive formulations and it consists of a complex mixture of substances, most of which are unknown. The resin has been reported to cause allergic contact dermatitis since the 1950s. LÄS MER
5. Synthesis of amino- and hydroxyl-substituted bridged bicyclic compounds and their application in asymmetric catalysis
Sammanfattning : In this work, hydroxyl- and amino-substituted bridged bicyclic compounds based on bicyclo[2.2.1]heptane, bicyclo[2.2. LÄS MER
