1. Development of new Catalytic Methods for the Selective Synthesis of Heterocycles
Sammanfattning : In the field of organic chemistry, the development of new catalytic methods for the synthesis of complex molecules from simple precursors is a top priority. The main focus of this thesis concerns the diastereoselective synthesis of heterocyclic compounds using main group elements as Lewis acid catalysts. LÄS MER
2. Palladium(0)-Catalysed Carbonylative Multicomponent Reactions : Synthesis of Heterocycles and the Application of Quinolinyl Pyrimidines as Enzyme Inhibitors
Sammanfattning : Palladium-catalysed carbonylative multicomponent reactions have proven useful for the synthesis of structurally diverse compounds. Carbon monoxide serves as an atom-efficient, one-carbon building block, which allows for further structural elaboration of the carbonyl compound. LÄS MER
3. Direct Catalytic Nucleophilic Substitution of Non-Derivatized Alcohols
Sammanfattning : This thesis focuses on the development of methods for the activation of the hydroxyl group in non-derivatized alcohols in substitution reactions. The thesis is divided into two parts, describing three different catalytic systems. LÄS MER
4. Novel monogalactoside galectin inhibitor scaffolds : Guiding selectivity with heteroaromatic interactions
Sammanfattning : Carbohydrates are involved in many cellular processes, and most biomolecules are glycosylated. Thesemodifications are used in biological systems as information carriers, helping regulate organization on the cell surfaceand interactions between cells and the environment. LÄS MER
5. Novel strategies for C-C/X bond formation
Sammanfattning : The formation of C-C/X bonds is essential for the manufacture of a broad range of chemicals and materials used in areas critical for maintaining quality of life in modern society, e.g. pharmaceuticals, agrochemicals and polymers, and for aspects of research in organic chemistry.
