  • A Diels-Alder approach to biaryl synthesis

    Creator:
    Ashburn, Bradley O.
    Abstract:
    An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

  • Studies on the biosynthesis of the streptolidine moiety of streptothricin F

    Creator:
    Wityak, John
    Abstract:
    The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

  • The Role of Materials Chemistry in Designing Advanced Color Inorganic Pigments

    Creator:
    Medina, Elena A.
    Abstract:
    The results of the research presented in this work are related to synthesis and investigations of novel color inorganic pigments having various structures and shades. Inorganic pigments play a major role in contemporary life. They are used in paints, rubber, plastic, cosmetics etc. Searching for new, stable, environmentally benign and...

    Creator:
    Waldenmaier, Pieter K.
    Abstract:
    This thesis is separated into three distinct projects. First, synthetic studies towards the furanosteroid viridin shown in part I. Second, synthetic studies towards the diperene obtusanal shown in part II. Third, the analysis, characterization, and synthesis of coronene derivatives towards their application in organic batteries shown in part III. Significant...

  • Synthesis of epothilones and epothilone analogues

    Creator:
    Sundermann, Kurt F.
    Abstract:
    A convergent synthesis of epothilone B that generates all seven of its asymmetric centers in a completely stereoselective fashion has been completed. Key reactions include an anti-Felkin aldol condensation to set the C6 and C7 stereochemistry, a directed α-hydroxylation to install the C15 (S)-hydroxyl substituent, and a Wittig condensation to...

  • Aqueous niobium chemistry at low pH : new precursors for oxide thin films

    Creator:
    Park, Deok-Hie
    Abstract:
    Phosphate and peroxide stabilize new oxo-hydroxo niobium clusters in water at low pH. The clusters open a new chapter in aqueous niobium chemistry under acidic conditions. The clusters also produce atomically smooth, amorphous niobium oxide phosphate (NbPOx) thin films. Reaction pathways from cluster solutions to amorphous niobium oxide phosphate solids...

  • Gene Activation Strategies in Filamentous Fungi for Natural Products Discovery

    Creator:
    Adpressa, Donovon A.
    Abstract:
    Fungi have long been a prolific source of clinically approved drugs. The antibiotic penicillin, the cholesterol lowering statins, and the immunosuppressant cyclosporine have changed the treatment of human diseases in the last century. Recently, genome analysis of filamentous fungi has revealed that the biosynthetic potential for natural product expression is...

  • Certain aspects of electron and coupled energy transfer in cardiac muscle

    Creator:
    Kettman, John Rutherford
    Abstract:
    The first area of investigation involves the electron transport of sub-mitochondrial particles and their components. The second area is the synthesis of ATP and other energy linked reactions and components of the energy conservation and transfer apparatus. Investigations on the nature of the tetramethyl-p-phenylenediamine (TMPD) shunt indicated that tetrachlorohydroquinone (TCHQ)...

  • Expanding the scope of a Diels-Alder approach to biaryl synthesis

    Creator:
    Schwartz, Johanna Perkins
    Abstract:
    A Diels-Alder approach to biaryls (DAB) has been applied towards the synthesis of highly substituted, programmable biaryl templates. Tri- and tetra-ortho-substituted biaryls can be produced in just three to four steps from commercially available materials utilizing the Diels-Alder [4+2] cycloaddition. The methods described herein will illustrate the ability of mono...
