    Abstract : This thesis deals with the development of new reaction methodology for stereoselective synthesis, as well as total synthesis of natural products and investigations of the stereochemical outcome in the Mukaiyama aldol reaction. Chapter 2 describes efforts made towards the total synthesis of the oxindole natural products perophoramidine and the communesin. READ MORE

  4. 12. Development of catalytic enantioselective C-C bond-forming and cascade transformations by merging homogeneous or heterogeneous transition metal catalysis with asymmetric aminocatalysis

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric catalysis; transition metals; aldehydes; heterogeneous catalysis; amino acid; organocatalysis; α-allylation; β-alkylation; dynamic transformations; polysubstituted; carbocycles; spirocyclic oxindoles; all-carbon quaternary stereocenters;

    Abstract : Chiral molecules play a central role in our daily life and in nature, for instance the different enantiomers or diastereomers of a chiral molecule may show completely different biological activity. For this reason, it is a vital goal for synthetic chemists to design selective and efficient methodologies that allow the synthesis of the desired enantiomer. READ MORE
