  1. 1. Alkylate Petrol. Environmental Aspects of Volatile Hydrocarbon Emissions

    Författare :Ulf Östermark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrocarbons; small engines; alkylate; alkenes; ethene; benzene; 3-butadiene; two-stroke engines; reformulated petrol; reformulated gasoline; 1;

    Sammanfattning : All hydrocarbons emitted from production and use of petrol are hazardous to human health and the environment, but to a different extent for individual compounds. This thesis compares and characterizes C2-C8 hydrocarbons related to alkylate petrol and conventional petrol. LÄS MER

  4. 3. Transition metal-catalysed hydrogen transfer processes for C-C and C-N bond formation : Synthetic studies and mechanistic investigations

    Författare :Agnieszka Bartoszewicz; Belen Martin-Matute; Martin Albrecht; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hydrogen transfer; catalysis; transition metal; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis focusses on synthetic studies and mechanistic investigations into reactions involving hydrogen-transfer processes.In the first part, the development of an efficient method for the synthesis of β-hydroxy ketones (aldols) and β-amino ketones (Mannich products) from allylic alcohols and aldehydes is described.

  5. 4. Design and synthesis of steroid mimetic libraries using solid phase techniques

    Författare :Marcus Ruda; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pyridone; quinolone; benzoindazole; solid phase chemistry; scavenger resin; combinatorial chemistry; alpha-arylation; nuclear hormone receptor; steroid mimetic.;

    Sammanfattning : This thesis deals with the design and synthesis of biologically active ligands for nuclear hormone receptors using combinatorial techniques. In the first part, a 5,6,6a,7,8,9,10,10a-octahydrobenzo[f]quinolin-3(4H)-one tricyclic core structure was designed mimicking the ABC-rings of a steroid. LÄS MER

  7. 5. Quantitative analysis of DNA adducts formed by some epoxides of industrial importance

    Författare :Kamila Plná; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :DNA adducts; 32P-postlabelling; cancer; genotoxicity; occupational; epoxides; allyl glycidyl ether; propylene oxide; epichlorohydrin;

    Sammanfattning : The work presented herein has focused on DNA adduct formation by three industrial epoxides, allyl glycidyl ether, propylene oxide and epichlorohydrin. Epoxides, owing to the strained oxirane ring are chemically reactive and can alkylate various sites in DNA. LÄS MER
