Dihalocarbene reactions with steroid olefins

Creator:: Cornelia, Richard Hartman
Abstract:: Dihalocarbenes have been generated mainly by thermal decomposition of sodium trihaloacetate and phenyl (trihalomethyl)mercury, and give gem-dihalocyclopropyl adducts with various steroid olefins. A new procedure involving the use of sealed tubes makes possible the addition of dihalocarbenes to sterically hindered olefins. In this manner, 7-cholestenyl benzoate when treated with PhHgCC1₃...

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.;...

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...

Gene Expression, Structure Elucidation, and Bioactivity of Aspergillus Natural Products

Creator:: Neuhaus, George F.
Abstract:: The study of natural products (NPs) and their application has shaped humanity. Starting with the idea of using plants as medicine, it has now grown into the science of purifying and identifying organic molecules from nature to study their inherent biological activities. Understanding the molecular structures of NPs is the...

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...

Active site studies and design of ligands for affinity column separation of 2,5-dihydroxyacetanilide epoxidase (DHAE) I and II

Creator:: Allen, Scott E.
Abstract:: A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electron density on inhibition. DHAE I gave a linear, highly correlated plot (r²=0.91) that signifies the...

Synthesis and oxidation of cysteine- and penicillamine- containing Fe(III) and Co(III) complexes. Analogs for the active metal sites of the cysteine and cysteamine dioxygenases

Creator:: Miller, Krys J.
Abstract:: The first part of this thesis describes a study of the characteristics of oxidation of a 1:2 iron(III):thiolate system in methanolic solution and in water. This system was investigated as a potential analog for the cysteine- and cysteamine-dioxygenase catalyzed 0₂-oxidation of cysteine and cysteamine, respectively, to the corresponding sulfinic acids....
