Part I: Synthetic Studies toward C10-functionalized Lycopodium Alkaloids. Part II: Exploration of the Pummerer Cyclization and Its Application to the Total Syntheses of the Abietane Diterpenoids

Creator:: Li, Xin
Abstract:: This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

Gas phase x-ray photoelectron spectroscopy of some ketone compounds

Creator:: Situmeang, Rudy T. M.
Abstract:: The photoelectron spectra of a series of ketone compounds have been investigated in the gas phase. Core ionization energies were measured to probe the effects of molecular size and connectivity number on core ionization energies. It was found that core ionization energies roughly decrease with increasing connectivity number as expected....

Time-of-flight scattering and recoil spectrometry (TOF-SARS) applied to molecular liquid surfaces : a new approach to surface composition and orientation

Creator:: Gannon, Thomas J.
Abstract:: In spite of their importance in many systems, liquid surfaces have been explored at the microscopic level to a much lesser extent than solids. Most surface analysis must take place in vacuum, a major drawback for liquids. The technique of time-of-flight scattering and recoil spectrometry (TOF-SARS) has been applied to...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

Total Synthesis of Tryptamine Alkaloids from the Arundo and Leuconotis Genera

Creator:: Ferreira, Andrew
Abstract:: The first part of this manuscript is about the total synthesis of the Arundo donax bis(indole) natural products. The A. donax alkaloids were prepared using the first example of an ynindole Diels–Alder reaction. Each were then separated, isolated, and determined to have stable enantiomeric conformations at room temperature (Chen, J.;...

Chemical labeling methods and mass spectrometry of mitochondrial thiol proteomes

Creator:: Wang, Jing
Abstract:: Dysfunction of mitochondria has been linked to aging and the pathogenesis of many degenerative diseases. Aside from their primary function in energy production, mitochondria are considered as a major source and target of reactive oxygen and nitrogen species (ROS/RNS) in cells as well. The mitochondrial thiol proteome is a subset...

The development and characterization of miniature spectrometers for measuring the redox status of environmental samples

Creator:: Cantrell, Kevin
Abstract:: A spectrometer, here denoted a Simple, Low-power, Inexpensive. Microcontroller-based or SLIM spectrometer. was developed that exploits the small size and low cost of solid-state electronic devices. This approach results in customizable spectrometers that are considerably less expensive and smaller than traditional instrumentation. The performance of the SLIM spectrometer was evaluated...

Synthesis and oxidation of metal-thiolate compounds which mimic the active site function of thiolate dioxygenase enzymes

Creator:: Schussel, Leonard J.
Abstract:: Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...
