  2. 2. Palladium(0)-Catalyzed Synthesis of Spirocycles and Supercritical Chemistry using a Resistively Heated Flow Reactor

    Författare :Ahmed Adeyemi; Mats Larhed; Luke R. Odell; Kenneth Wärnmark; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Continuous Flow; Resistive heating; Supercritical fluids; high-temperature synthesis; Mizoroki-Heck reaction; Spirooxindoles; Spiroethers; Spirobenzofuranes; Unnatural Amino Acids;

    Sammanfattning : This doctoral thesis focusses on an effective and selective approach to the synthesis of spirocycles using palladium(0)-catalyzed Mizoroki-Heck reactions. In addition, selective and efficient chemistry was highlighted by the design and evaluation of a novel resistively heated system for continuous flow (CF) synthesis for high-temperature and high-pressure applications.

  5. 5. Development of HIV-1 Protease Inhibitors and Palladium-Catalyzed Synthesis of Aryl Ketones and N-Allylbenzamides

    Författare :Linda Axelsson; Mats Larhed; Anders Karlén; Luke Odell; Morten Grötli; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; palladium; aminocarbonylation; aryl ketones; decarboxylation; HIV; protease inhibitor; tertiary alcohol; macrocycles; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : The use of palladium-catalyzed reactions to introduce new carbon-carbon bonds is a fundamental synthetic strategy that has been widely embraced due to its high chemo- and regioselectivity and functional group tolerance. In this context, Pd(0)-catalyzed aminocarbonylations using Mo(CO)6 instead of toxic and gaseous CO and with allylamine as the nucleophile were investigated. LÄS MER
