  3. 2. Controlling the Reactivity and Selectivity in Iridium- and Rhodium-Catalyzed Asymmetric Hydrogenation

    Författare :Haibo Wu; Pher Andersson; Virginie Ratovelomanana-Vidal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asymmetric hydrogenation; Cascade reaction; Kinetic resolution; Desymmetrization; Dearomatization; Total synthesis; Heterogeneous catalysis; organisk kemi; Organic Chemistry;

    Sammanfattning : The work presented in this thesis is mainly focused on the development of iridium- or rhodium-catalyzed asymmetric hydrogenation featuring a number of practical concepts including cascade reaction, kinetic resolution, desymmetrization, and dearomatization. The protocols rely on gaining control of the reactivity among different olefins or olefin precursor as well as maintaining chemo- and stereo-selectivity in the hydrogenation. LÄS MER
