  1. 1. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State

    Author : Giovanny A. Parada; Sascha Ott; Ana Moore; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Solar energy conversion; artificial photosynthesis; hydrogen bonds; excited state intramolecular proton transfer; tautomerization; proton-coupled electron transfer; photosensitizer; ruthenium complex.; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. READ MORE

  2. 2. A Chemical Approach Toward the Therapeutic Optimization of Cytotoxic Bioconjugates

    Author : Rafael Hartmann; Luke R. Odell; Fredrik Lehmann; Mats Larhed; Dario Neri; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chemotherapy; antibody-drug conjugates; organic synthesis; bioorganic chemistry; synthetic method development; analytical method development; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi; Medicinal Chemistry; Läkemedelskemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The delivery of cytotoxicity to specific cells was recognized to be the key to the effective, chemical treatment of infectious and neoplastic diseases well over a century ago. In the context of oncology, the primary therapeutic challenge is the distinction between healthy and pathological cells despite their pronounced pheno- and genotypic similarity. READ MORE

  3. 3. Palladium-Catalysed Couplings in Organic Synthesis : Exploring Catalyst-Presenting Strategies and Medicinal Chemistry Applications

    Author : Alejandro Trejos; Mats Larhed; Jianliang Xiao; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mizoroki-Heck arylation; Suzuki coupling; domino reaction; stereoselective; palladium; chelation control; vinyl ether; HIV-protease inhibitors; HIV-integrase inhibitors; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Abstract : Palladium-catalysed coupling reactions have been embraced by synthetic chemists as one of the preferred means for smooth formation of new carbon-carbon bonds: a truly ubiquitous methodology of synthesizing complex molecules.This thesis describes the study of a series of palladium(0)-catalysed C2-arylations of a 1-cyclopentenyl ether, equipped with a chiral (S)-N-methyl-pyrrolidine auxiliary.
