  2. 1. Green Chemistry in Chemical Education and Synthetic Applications of Sulfinamides

    Author : Björn Blomkvist; Peter Dinér; José Alemán; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sulfinamide; Green Chemistry; Chiral Auxiliary; Photoredox; Teaching; Sulfinamid; Grön Kemi; Kiral Hjälpgrupp; Fotoredox; Undervisning; Kemi; Chemistry;

    Abstract : The preparation of chiral molecules, i.e. compounds that are not identical to their mirror image, is of great interest in the field of organic chemistry. READ MORE

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

    Author : Fredrik Ek; Centrum för analys och syntes; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Synthesis and applications of analogues of Tröger's base as molecular tubes, receptor and ligands

    Author : Anna Hansson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Organic chemistry; bis-crown ether analogue; molecular recognition; molecular tubes; Tröger s base; dihalo-analogues;

    Abstract : Tröger’s base was synthesized for the first time in 1887. The molecule is rigid, C2-symmetric and has a 90° angle, forming a chiral hydrophobic pocket. In this thesis, the synthesis of new analogues of Tröger’s base is described. 2- and 3-halo-substituted anilines have for the first time been condensed to Tröger’s base analogues. READ MORE

  6. 4. Synthesis of Spiro-bicyclo[2.2.2]Octane Derivatives Towards the Development of Paclitaxel Mimetics

    Author : Viveca Thornqvist; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Organic chemistry; Organisk kemi; Chemistry; Natural science; paclitaxel; spiro; indium; Naturvetenskap; bicyclo[2.2.2]octane; allylation; paclitaxel mimetic;

    Abstract : Many of the drugs that are developed in the pharmaceutical industry have their origin in natural products. Paclitaxel, the active substance of the medicine Taxol, was found in the bark of the Pacific yew tree (Taxus brevifolia). READ MORE
