    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

  3. 17. Bispyridylamides as ligands in asymmetric catalysis

    Författare :Oscar Belda de Lama; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; chiral ligand; pyridine; amide; allylic alkylation; enantioselective; cyanation; ring-opening; chiral Lewis acid;

    Sammanfattning : This thesis deals with the preparation and use of chiralbispyridylamides as ligands in metal-catalyzed asymmetricreactions. The compounds were prepared by amide formation usingdifferent coupling reagents. LÄS MER

  4. 18. Asymmetric Oligothiophenes : Chemical Evolution of Multimodal Amyloid Ligands

    Författare :Leif B.G. Johansson; Peter Nilsson; Peter Konradsson; Mikael Elofsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Luminescent conjugated polymers (LCPs) and luminescent conjugated oligothiophenes (LCOs) can be used as molecular probes to study diseases associated with protein aggregation. The conventionally used dyes to study and detect protein aggregates, denoted amyloid, have been Congo red (CR) and Thioflavin T (ThT). LÄS MER
