  2. 1. Iridium Catalysed Asymmetric Hydrogenation of Olefins and Isomerisation of Allylic Alcohols

    Author : Byron Peters; Pher Andersson; Andreas Pfaltz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Abstract : The work described in this thesis is focused on exploring the efficacy of asymmetric iridium catalysis in the hydrogenation of challenging substrates, including precursors to chiral sulfones and chiral cyclohexanes. Furthermore, iridium catalysis was used to isomerise allylic alcohols to aldehydes, and in a formal total synthesis of Aliskiren (a renin inhibitor). READ MORE

  4. 2. Ruthenium-Catalyzed Hydrogen Transfer Reactions : Mechanistic Studies and Chemoenzymatic Dynamic Kinetic Resolutions

    Author : Madeleine Warner; Jan-Erling Bäckvall; Andreas Pfaltz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen transfer; ruthenium catalysis; kinetic resolution; dynamic kinetic resolution; racemization; asymmetric synthesis; organisk kemi; Organic Chemistry;

    Abstract : The main focus of this thesis lies on transition metal-catalyzed hydrogen transfer reactions. In the first part of the thesis, the mechanism for racemization of sec-alcohols with a ruthenium complex, Ru(CO)2Cl(η5-C5Ph5) was studied. READ MORE
