  4. 3. Photochemical Ligation Techniques for Carbohydrate Biosensors and Protein Interaction Studies

    Författare :Oscar Norberg; Olof Ramström; Stéphane Vincent; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; Biosensors; CuAAC; Photochemistry; Thiol-ene yne; Perfluorophenylazide PFPA ; Lectins; Molecular recognition; Quartz crystal microbalance QCM ; Surface plasmon resonance SPR ;

    Sammanfattning : This thesis concerns the development of surface ligation techniques for the preparation of carbohydrate biosensors. Several methodologies were developed based on efficient photochemical insertion reactions which quickly functionalize polymeric materials, with either carbohydrates or functional groups such as alkynes or alkenes.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbocyclization; Palladium catalysis; Oxidation; Enallenes; Enynes; Borylation; Arylation; Asymmetric Catalysis; Chiral Brønsted acids; Chiral anion; organisk kemi; Organic Chemistry;

    Sammanfattning : Transition metal catalysis has emerged as one of the most versatile methods for the selective formation of carbon–carbon and carbon–heteroatom bonds. In particular, oxidative carbon–carbon bond forming reactions have been widely studied due to their atom economic feature. LÄS MER

  7. 5. Investigations of selectivity control in catalysis

    Författare :Henrik von Schenck; KTH; []
    Nyckelord :;

    Sammanfattning : Catalytic reactions are ever present in applied chemistry,from laboratory synthesis to industrial scale processes.Catalysts provide the means to influence both the rate ofreactions (activity) and the product outcome (selectivity),thereby having fundamental impact on the reaction efficiency.
