  1. 1. Bispidine derivatives as molecular tools for studies of (-Allyl)palladium complexes : Ligand synthesis and analythical cpplications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Andreas Axén; Uppsala universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Determination of structural and stereochemical features of reaction intermediates in transition metal catalysed reactions is of central interest. Bispidine derivatives as ligands in (π-allyl)palladium complexes in combination with 1H NMR spectroscopy are shown to be useful tools for revealing structural characteristics of these reaction intermediates.

    Sammanfattning : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of silicon, and therefore the computing power, will double every 18 to 24 months. For the last 40 years Moore’s prediction has held true as computers have grown more and more powerful. LÄS MER

    Sammanfattning : Galectins, a lectin family, have shown binding affinities towards b-galactosides. Galectins have been proposed to be involved in a wide range of functions like for example, cell growth, adhesion, migration, chemo taxis and apoptosis. They have also been associated with various cancer types. LÄS MER

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

    Detta är en avhandling från Chalmers University of Technology

    Författare :Magnus Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk syntes; Organic synthesis; asymmetric synthesis; borane; chirality; cytisine; desymmetrization; enantioselective cyclopropanation. enantioselective deprotonation; gold I catalysis lipase; P-chirogenic; phosphine;

    Sammanfattning : Abstract This 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
