2. Serotonergic aporphine derivatives : Synthesis and structure-activity relationships
Abstract : Novel series of well-characterized and stereochemically pure 11-substituted (R)-aporphine derivatives have been prepared and their interaction with serotonin 5-HT7 and 5-HT1A receptors and dopamine D2A and D1 receptors have been studied. Efficient palladium catalyzed reactions were utilized for the diastereoselective synthesis of atropisomers as well as for the synthesis of several of the other (R)-aporphine derivatives. READ MORE

3. Crystallographic Studies of Ternary Chalcogenides and Organic Semiconductors
Abstract : X-ray diffraction methods have been used to study the crystal structure of different compounds, both organic and inorganic. The inorganic compounds were all synthesized by solid state reactions. A new compound, Re4As6S3, was synthesized and its structure was solved by Rietveld methods. READ MORE

4. Amino acid-catalyzed synthesis of amino acid derivatives : Application and semi-synthesis of Paclitaxel, Docetaxel and their derivatives
Abstract : This thesis deals with different applications of organocatalysis, where amino acid derivatives and small peptides are applied as catalysts. First, the development of environmentally friendly aldol reactions, carried out in aqueous media is illustrated. The corresponding β-hydroxy ketones are formed with ee´s up to 99%. READ MORE

5. Pricing Portfolio Credit Derivatives
Abstract : This thesis consists of four papers on dynamic dependence modelling in portfolio credit risk. The emphasis is on valuation of portfolio credit derivatives. The underlying model in all papers is the same, but is split in two different sub-models, one for inhomogeneous portfolios, and one for homogeneous ones. READ MORE
