  3. 2. New Arylation Strategies Based on Organomain Group Reactivity

    Författare :Carina Sollert; Lukasz T. Pilarski; Brenton L. DeBoef; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C-H functionalisation; catalysis; ruthenium; indole; silylation; boronate; boryl aryne; aryne distortion; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : The work in this thesis describes the development of new heteroarylation methodology based on transition metal-catalysed C-H functionalisation and the properties of organomain group compounds. The underlying reaction mechanisms and reactivity patterns of the (hetero)arene substrates are also investigated. LÄS MER

  5. 4. Synthesis Towards Biologically Active Natural Products

    Författare :Rikard Larsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transtaganolide; basiliolide; natural product; total synthesis; biomimetic; Thapsia; Diels-Alder; Ireland-Claisen; Pictet-Spengler; tetrahydroisoquinoline; indole;

    Sammanfattning : In 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. LÄS MER

  7. 5. Polyesters with indole as sustainable aromatic component

    Författare :Ping Wang; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; indole; sustainable polyesters; high performance; recycling; biodegradation;

    Sammanfattning : Plastics are widely used in our daily lives and industry. Unfortunaltely, most plastics are produced from non-renewable fossil resources. The transition toward sustainable resources such as various biomass is critically important for the future of plastic industry and the whole society. LÄS MER
