Deantiaromatization as a driving force in an electrocyclization of cyclopentadienone and the total synthesis of 1-epi-esco-pseudopteroxazole
(University of Missouri--Columbia, 2007)Deantiaromatization has been successfully demonstrated as a driving force in an electrocyclization of cyclopentadienones. The reaction was found to be general for a number of substrates and provides a unique way to access ... -
Determination of total selenium and seleno-amino acids in yeast and aquatic organisms by liquid chromatography and inductively coupled plasma mass spectrometry
(University of Missouri--Columbia, 2007)The primary goal of this dissertation research was to develop methods for routine speciation analysis of selenium in tissues. A method for total selenium using on-line stable isotope dilution analysis with conventional ... -
Diels-alder reactions of a cyclopentadienone derivative
(University of Missouri--Columbia, 2007)An ester derivative of cyclopentadienone, a very reactive species, was generated from methyl-2-bromo-3-oxocyclopent-1-enecarboxylate (96) which dimerized instantaneously and decarbonylated to generate an indanone (97). ... -
The effects of structural modifications on sigma receptor binding
(University of Missouri--Columbia, 2007)The sigma receptor is a unique receptor family that has two subtypes: sigma1 and sigma2. Sigma1 receptors are involved in several physiological functions such as psychosis and depression. Sigma2 receptors are expressed in ... -
Energy transfer at gas-liquid interface : towards energetic materials
(University of Missouri--Columbia, 2007)Physicochemical surface processes have great importance in the different fields of everyday life and science. Computational characterization of collisional energy transfer at a gasliquid interface is a helpful tool to ... -
From carbon to copper : studies of novel nanomaterials
(University of Missouri--Columbia, 2007)Nanomaterials are materials on the order of 10-9 m that are currently being investigated for use in a wide range of applications in the growing field of nanotechnology. This dissertation documents the synthesis, characterization, ... -
Molecular dynamics simulations of pressure shocks in liquid phase nitromethane
(University of Missouri--Columbia, 2007)The dynamic energy transfer processes present in liquid nitromethane (NM) under pressure shock loading conditions have been investigated by nonequilibrium molecular dynamics methods using a previously developed, fully ... -
Phosphinimines as potential technetium environmental sensors
(University of Missouri--Columbia, 2007)Phosphinimines, R₃P=NSiMe₃, undergo hydrolysis to form the phosphiniminiumcation, R₃P=NH₂+, which forms the ion pair [R₃P=NH₂+][X-] in the presence of an anion.Preliminary studies show that in the presence of TcO₄-, ... -
Probing supramolecular assemblies via fluorescent reporter molecules
(University of Missouri--Columbia, 2007)Supramolecular, self-assembled nanocapsules have shown the capability to encapsulate organic guests. Since most of the work was done previously in the solid state, the novelty of this research was its focus on probing ... -
Structural studies of acid phosphatases from pathogenic bacteria
(University of Missouri--Columbia, 2007)Acid phosphatases are important, ubiquitous, and diverse group of enzymes that catalyze the transfer of phosphoryl from phosphomonoester to water forming inorganic phosphate and alcohol. These enzymes play critical roles ... -
Synthesis and structure-activity relationship of a series of sigma receptor ligands
(University of Missouri--Columbia, 2007)Sigma receptors are involved in several biological processes, and sigma ligands might be promising as cancer treatment agents, cocaine abuse medicines, and valuable psychiatric drugs. In an attempt to elucidate effectual ...
