  1. 1. Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds

    Författare :Fredrik Ek; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bengamide analogue.; parallel synthesis; trimethylsilyl azide; cycloaddition; imidazole; fused tetrazole derivatives; iodocyclization; benzazepine; tert-butyl nitrite; allylic bromide; aromatic allylation; diazotization; Organic chemistry; Organisk kemi;

    Sammanfattning : A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. LÄS MER

  3. 2. Novel Pincer Complex-Catalyzed Transformations : Including Asymmetric Catalysis

    Författare :Juhanes Aydin; Kálmán J. Szabó; Oleg V. Ozerov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pincer; palladium; catalysis; chiral; asymmetric; palladium IV; allylation; aldol; aminoacid; C-H functionalization; cross-coupling; homoallylic; heck reaction; tridentate ligand; Chemistry; Kemi; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis is focused on the development of new pincer complex-catalyzed transformations. Optimization of the catalytic properties (fine-tuning) was directed to increase the catalytic activity as well as the chemo-, stereo- and enantioselectivity of the complexes. LÄS MER

  4. 3. Fine-tuning of the catalytic activity and selectivity of palladium pincer complexes

    Författare :Juhanes Aydin; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is focused on optimization of the catalytic properties of so-called pincer complexes. This work involved synthesis of a large variety of palladium pincer complexes, which were applied in various organic transformations. LÄS MER
