  2. 1. Methods for Asymmetric Olefination Reactions; Development and Application to Natural Product Synthesis

    Author : Daniel Strand; Tobias Rein; Viresh Rawal; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antitumor agents; Asymmetric Horner-Wadsworth-Emmons; Desymmetrization; Metal-catalyzed olefination; Mucocin; Palladium-catalyzed allylic substitution; Parallel kinetic resolution; Pyranicin; Pyragonicin; Rhenium; Stereoconvergent synthesis; Stereodivergent synthesis; Stereoselective synthesis; Tetrahydropyran; Wittig reaction; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the development and application of methods for asymmetric olefinations, in particular Horner-Wadsworth-Emmons (HWE) reactions, in the synthesis of certain natural products. Relying on asymmetric HWE reactions to access key building blocks, two natu-ral products, pyranicin and pyragonicin, were synthesized from common late intermediates. READ MORE

  6. 4. Genomic feature identification in trypanosomatid parasites

    Author : Daniel Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Trypanosoma cruzi; genome sequence; bioinformatics; gene finding; Trypanosoma brucei; Leishmania major; strand asymmetry; trans splicing; polyadenylation; post-transcriptional control; uAUGs.;

    Abstract : The trypanosomatid parasites cause death and suffering, among humans as well as livestock. Current drugs lack efficacy and cause severe side effects, and no vaccines are available. Increased knowledge of the biology of the parasites is vital for the development of new drugs. READ MORE
