  • An approach toward the synthesis of euonyminol and cathedulin K- 19

    Creator:
    Shin, Hyunik
    Abstract:
    A synthetic approach toward the two major fragments of cathedulin K-19, euonyminol (4) and dimethyl cathate (69), was investigated. Synthesis of dimethyl cathate was accomplished in 3 steps starting from 73. Efforts directed towards the synthesis of euonyminol, a highly oxygenated dihydroagarofuran sesquiterpene, was advanced to a stage in which...

  • A chemical study of the minerals from L-6 chondritic meteorites

    Creator:
    Curtis, David Ballantyne
    Abstract:
    Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

  • Fundamental Studies of the Structure-Property Correlations of Na-ion and K-ion Storage in Non-Graphitic Carbon

    Creator:
    Li, Zhifei
    Abstract:
    Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...

  • Progress Towards the Total Synthesis of Bazzanin K

    Creator:
    Salvo, Patrick
    Abstract:
    Molecular chirality plays a critical role in chemistry, biology, and medicine. To study and better understand conformational chirality, it is necessary to obtain structurally interesting molecules that exhibit this form of chirality. Our lab utilizes total synthesis and methodological development to obtain conformationally chiral natural products of interest. We believe...

  • The use of the Diels-Alder reaction in asymmetric synthesis

    Creator:
    Dei Rossi, Dale Raymond
    Abstract:
    The Diels-Alder reaction represents a promising tool for use in asymmetric synthesis. The reaction involves a rigid transition state that facilitates the formation of one diastereomeric transition state and is reversible. This satisfies two necessary criteria for asymmetric synthesis. The Diels-Alder reactions of 1,l-dialkylspiro[2.4]-4,6- heptadienes with maleic anhydride and p-benzoquinone...

  • Atmospheric transport of anthropogenic semi-volatile organic compounds to the Olympic Peninsula of Washington State

    Creator:
    Killin, Robert K.
    Abstract:
    Ambient high-volume (hi-vol) air samples were collected between March 15th and May 30th 2002, at Cheeka Peak Observatory (CPO), located on the tip of the Olympic Peninsula, Washington State. This sampling campaign was in conjunction with the 2002 Inter-Continental Transport and Chemical Transformation (ITCT 2K2) Campaign and the Photochemical Ozone...

  • Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

    Creator:
    Ackerman, Luke K.
    Abstract:
    Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...

  • Total Synthesis of Cephalotaxus Alkaloids and Synthetic Studies toward Bazzanin K

    Creator:
    Ju, Xuan
    Abstract:
    Dearomatization reactions exist broadly in biosynthesis and chemical synthesis. The highly functionalized atoms of arenes can be masked by it aromaticity, and upon dearomatization, those reactive atoms can be readily applied to bond formation and further manipulation. The total synthesis of (–)-cephalotaxine and (–)- homoharringtonine is described via an oxidative...

  • The photochemistry of some O-(methylcarbamoyl) oximes

    Creator:
    McCarthy, Kermit D.
    Abstract:
    The photochemistry of aldicarb and two related compounds, 0-(methylcarbamoyl) isobutyraldehyde oxime and 0-(methylcarbamoyl) trimethylacetaldehyde oxime was explored under laboratory conditions. Upon irradiation aldicarb decomposed rapidly to methylamine, dimethylamine, tetramethylsuccinonitrile, and 1-methylthio-2, 3-dicyano-2, 3-dimethylbutane. The other two compounds decomposed only after a long period of irradiation. The difference in reactivity was...
