21. Synthesis and evaluation of bicyclic 1,3-diols (BODOLs) as ligands for asymmetric catalysis
Sammanfattning : Several ligands based upon 2-substituted bicyclic[2.2.2]octane-2,6-diols (BODOLs) were synthesized and evaluated in two catalytic reactions: I) the Ti(IV)-mediated catecholborane asymmetric reduction of prochiral ketones and II) as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes.

22. Computational Modelling of Structures and Ligands of CYP2C9
Sammanfattning : CYP2C9 is one of our major drug metabolising enzymes and belongs to the cytochrome P450 (CYP) super family. The aim of this thesis was to gain an understanding of the quantitative structure–activity relationships (QSAR) of CYP2C9 substrates and inhibitors. LÄS MER
23. Development of New Chiral Bicyclic Ligands : Applications in Catalytic Asymmetric Transfer Hydrogenation, Epoxidations, and Epoxide Rearrangements
Sammanfattning : This thesis describes the synthesis and application of new chiral bicyclic ligands and their application in asymmetric catalysis. The studies involved: [i] The development of novel chiral bicyclic amino sulfur ligands and their use in transfer hydrogenation. LÄS MER
24. C–H activation through late transition metal cyclometallation. Addressing selectivity and reactivity problems
Sammanfattning : The ligand-directed C—H activation relies on a coordinating donor atom being in proximity to the C—H bond activated. Cyclometallation of 2-(1-naphthyl)-pyridine – a substrate containing both γ- and δ-positions in proximity to the directing nitrogen atom – was studied. LÄS MER
25. Design, Synthesis and Thermodynamic Studies of Galectin Ligands
Sammanfattning : The signaling within and between cells in biology is governed by molecular recognition between natural or synthetic ligands and proteins. This thesis project aimed to investigate the thermodynamic properties of specific interaction between synthetic ligands and galectin proteins. LÄS MER
