  1. 6. Synthesis of chiral allyl and propargyl boronates by organocatalytic carbene insertion to carbon-boron bonds

    Författare :Marie Deliaval; Kálmán Szabó; Fahmi Himo; Carlos Valdés; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boron; asymmetric synthesis; organocatalysis; allylic compounds; allenols; Organic Chemistry; organisk kemi;

    Sammanfattning : This thesis describes the development of a novel organocatalytic method for the synthesis of chiral allyl- and propargyl- organoboron compounds with high enantioselectivity. These organoboron species are versatile building blocks in asymmetric synthesis.We have developed a new efficient homologation method of alkenyl boronic acids. LÄS MER

  3. 7. Multifunctional Polymer Materials: From Synthesis to Disinfection

    Författare :Haiyue Gong; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymer; Antibacterial; Ag nanoparticles; Antibiotic; Boronic acid; Polyethylenimine; Quaternary ammonium;

    Sammanfattning : Polymer materials have wide applications in many industries, such as the food, pharmacy, construction, textile, and cosmetics industries. For the past few years, polymer materials have drawn the attention of scientists and engineers as a good disinfectant due to their advanced manufacturing methods, large surface areas, good stability, and lowcost.

  4. 8. Copper and Palladium-Mediated Transformationsof Allylic and Propargylic Substrates

    Författare :Tony S. N. Zhao; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis is focused on the development of new palladium and copper-mediated reactions for functionalization of alkenes and propargylic alcohol derivatives. We have developed an efficient procedure for the synthesis of allenyl and propargyl boronate from propargylic carbonates and acetates. LÄS MER

  5. 9. Selective Sorbents - Silica-immobilized affinity ligands and molecularly imprinted polymers

    Författare :Magnus Glad; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular imprinting; HPLAC; composites; TRIM; Biokemi; Biochemistry; Metabolism; affinity chromatography;

    Sammanfattning : The development of selective sorbents for the separation of various molecules, preferentially biomolecules, is described in this work. Affinity ligands were immobilized on small silica particles and used in high-performance liquid affinity chromatography (HPLAC). LÄS MER

  7. 10. The three-component aza-Baylis-Hillman reaction : development and application

    Författare :Daniela Balan; Hans Adolfsson; Varinder Aggarwal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The current thesis presents the optimization and generalization of the Baylis-Hillman reaction applied to in situ generated imines, i.e. a three-component aza- Baylis-Hillman reaction. We found that the title reaction proceeds most efficiently in the presence of a combination of catalysts, i. LÄS MER
