  1. 31. Palladium(0)-Catalysed Carbonylative Multicomponent Reactions : Synthesis of Heterocycles and the Application of Quinolinyl Pyrimidines as Enzyme Inhibitors

    Författare :Linda Åkerbladh; Mats Larhed; Luke Odell; Anders Karlén; Lise-Lotte Gundersen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Palladium catalysis; Carbonylation; Multicomponent reactions; Domino reactions; Heterocycles; 4-Quinolones; 2-Aminoquinazolinones; Benzoxazinones; N-Acylguanidines; Type II NADH dehydrogenase; NDH-2;

    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. 32. Synthesis and Applications of P-chirogenic Phosphine Boranes

    Författare :Magnus Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytisine; gold I catalysis lipase; P-chirogenic; desymmetrization; phosphine; enantioselective cyclopropanation. enantioselective deprotonation; chirality; asymmetric synthesis; borane;

    Sammanfattning : AbstractThis thesis reports the independent synthesis of both enantiomers of P-chirogenic phosphine ligands and the building blocks thereof, which are suitable for parallel synthesis efforts and for the generation of more diverse libraries of P-chirogenic compound. The use of P-chirogenic phosphine boranes in transition metal-catalyzed reactions, such as palladium-catalyzed allylic alkylation and amination, is also described. LÄS MER

  4. 33. Methodological advancements in microfluidic and carbonylation PET radiochemistry

    Författare :Kenneth Dahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Along with the progress of PET as a powerful imaging tool in medicine, there has been increasing demand for new labeling methods. The main aim of this PhD dissertation was to develop novel labeling methodologies using the positron emitter carbon-11. LÄS MER
