  1. 1. Self-adaptable catalysts : Importance of flexibility and applications in asymmetric catalysis

    Författare :Ester Fjellander; Christina Moberg; Jay Siegel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; adaptable; flexible; semi-flexible; symmetry; conformational study; mechanistic study; rotation barrier; VT NMR; asymmetric catalysis; ligand design; allylic alkylation; hydrogenation; azepines; dioxaphosphepines; phosphepines; amines; phosphines; phosphoramidites; phosphinites; palladium; rhodium; Organic chemistry; Organisk kemi;

    Sammanfattning : The topic of this thesis is the design and synthesis of biaryl-based self adaptableligands for asymmetric metal catalysis. The results discussed in papers I-III are covered, together with some unpublished results concerning substrate-adaptable catalysts. A general survey of self-adaptable catalysts is presented first.

  5. 4. Iron Carbonyl Mediated Parallel Synthesis

    Författare :Henrik Gradén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dienyl; scavenger; solid phase; galectin inhibitor; oseltamivir; iron carbonyl complex; polymer bound reagent; cation; linker; parallel synthesis; active ester;

    Sammanfattning : This thesis describes the examination and development of cationic iron carbonyl complexes for use in parallel synthesis both in solution phase and on solid phase. A solution phase methodology for carbon-carbon and carbon-heteroatom formation, utilizing polymer bound reagents and scavengers and amenable for automation has been successfully developed. LÄS MER

  7. 5. Structural and functional investigation of underexplored carbohydrate-active enzyme families

    Författare :Andrea Seveso; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbohydrate-active enzymes; lytic polysaccharide monooxygenase; plant biomass degradation; copper radical oxidases; carbohydrate esterase; protein structure determination; protein structure prediction;

    Sammanfattning : The known consequences of the current fossil-based economy require a transition towards a bio-based economy. Development of biorefineries in which plant biomass can be utilized as a renewable source of energy and building blocks to produce both commodities and high-value products, is a key step in this transition.
