  1. 1. Catalytic Regio- and Stereoselective Reactions for the Synthesis of Allylic and Homoallylic Compounds

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Rauful Alam; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium catalysis; C−H functionalization; boronic acid; allylboration; asymmetric catalysis; allylic; homoallylic; diastereoselective; enantioselective; Organic Chemistry; organisk kemi;

    Abstract : This thesis is focused on two main areas of organic synthesis, palladium-catalyzed functionalization of alkenes and allylic alcohols, as well as development of new allylboration reactions.We have developed a palladium-catalyzed selective allylic trifluoroacetoxylation reaction based on C−H functionalization.

  2. 2. Carbohydrate-specific, boronate-containing copolymers: from sugar-sensing to cell adhesion

    University dissertation from Lund University (Media-Tryck)

    Author : Marina Kuzimenkova; Lunds universitet.; Lund University.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface grafting; chemisorption; boronic acid; carbohydrates; affinity; chromatography; smart polymers; biomimetics; hydrogels; molecular recognition; diffusion; sugar-sensing; cell adhesion;

    Abstract : Carbohydrates play a major role in many cell recognition events and metabolic pathways of living organisms. Synthetic carbohydrate receptors are of great interest for the chemical design of sugar sensors, materials for cell separation, cell immobilization, drug delivery and other biomedical/biotechnological applications.

  3. 3. Palladium(II)-Catalyzed Oxidative Carbocyclization/Functionalization of Allenynes

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Teresa Bartholomeyzik; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palladium catalysis; oxidation; carbocyclization; allenynes; boron reagents; kinetics; selectivity; reaction mechanism; Organic Chemistry; organisk kemi;

    Abstract : The selective formation of carbon-carbon bonds constitutes a key transformation in organic synthesis with useful applications in pharmaceutical or material industry. A particularly versatile tool for carbon-carbon as well as carbon-heteroatom bond formation is palladium catalysis, which allows for mild and selective routes even towards complex structures.

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

    University dissertation from Magnus Glad, Nyckelkroken 64, SE-226 47 Lund, Sweden

    Author : Magnus Glad; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular imprinting; HPLAC; composites; TRIM; Biokemi; Biochemistry; Metabolism; affinity chromatography;

    Abstract : 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). READ MORE

  5. 5. Structure analysis and molecular recognition studies of bio-functionalized surfaces

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Cecilia Vahlberg; Linköpings universitet.; Linköpings universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Biological and chemical reactions involved in physiological processes are often complex and very sophisticated. Such processes can be mimicked in the laboratory to obtain important knowledge, valuable for the  development of new diagnostic methods, drugs and biosensors. READ MORE
