  2. 21. Oxidative Trifluoromethylation and other Functionalization Reactions of Alkenes and Alkynes

    Author : Pär Janson; Kálmán Szabó; Antonio Togni; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium; copper; transition metal; trifluoromethylation; catalysis; acetoxylation; difunctionalization; oxidation; mechanistic study; alkenes; alkynes; quinones; organisk kemi; Organic Chemistry;

    Abstract : This thesis concerns the use of various potent oxidants in organic synthesis. The main focus is directed at selectively introducing trifluoromethyl groups into compounds containing double or triple bonds. All reactions proceed under mild conditions and can in most cases be performed on the bench-top. READ MORE

  4. 22. Monoterpenes from the boreal coniferous forest : their role in atmospheric chemistry

    Author : Robert Janson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The goal of this work has been to increase our knowledge of the role of the monoteipenes emitted by the boreal coniferous forest in atmospheric chemical processes. To this end, measurements of air concentrations and emission rates have been made in forests of Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) at 4 sites throughout Sweden, during the summers of 1989 and 1990.

  7. 25. Cisplatin-resistance and cell death in malignant pleural mesothelioma cells

    Author : Veronica Janson; Kjell Grankvist; Roger Henriksson; Parviz Behnam-Motlagh; Anders Johansson; Boris Zhivotovsky; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; BH3-only proteins; caspase; cell morphology; potassium transport; protein kinase B PKB Akt ; signalling pathways; time; Clinical chemistry; Klinisk kemi;

    Abstract : Malignant pleural mesothelioma (MPM) is an aggressive, treatment-resistant tumour. Cisplatin (cis-diamminedichloroplatinum (II)) is the best single-agent chemotherapy for MPM, but platinum-based combination therapies give the best overall response rates. However, cisplatin use is limited by resistance and severe side effects. READ MORE
