Thresholds of uncertainty : radiation and responsibility in the fallout controversy

Creator:: Jolly, J. Christopher
Abstract:: The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...

Stereoselective synthesis & application of enantioenriched main group α-haloalkyl organometal reagents

Creator:: Emerson, Christopher R.
Abstract:: Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes. Abstract for...

Identification of candidate genes for survival and their use in predicting field performance of Pacific oyster Crassostrea gigas families in coastal waters

Creator:: Lang, Robert Paul
Abstract:: Summer mortality of farmed Pacific oysters causes financial losses for shellfish growers, and selective breeding to improve survival of offspring is a promising way to reduce losses. This dissertation has two objectives to assist the development of tools for use in selective breeding programs. Objective 1: Identify candidate genes for...

Conformationally chiral diphenylethers and the enantioselective Ullmann etherification

Creator:: Salih, M. Quamar
Abstract:: Since the discovery of molecular chirality in 1848, this notion has had a substantial impact on medicine, biology, and chemistry. Extensive effort has been directed towards the construction of chiral molecules that contain sp³ hybridized stereogenic centers. In contrast, less effort has been dedicated to molecules that are chiral by...

Biochemical effects of tumorigenic enhancers

Creator:: Christopher, John Paul
Abstract:: 2 -acetylaminofluorene -induced hepatocarcinogenesis in rats proceeds in stages of initiation and promotion, similar to experimental systems, in mouse skin. In this study promoters of liver tumorigenesis, phenobarbital, DDT and butylated hydroxytoluene (BHT), were compared to non-promoters, amobarbital, diphenylhydantoin (DPH) and benz(a)anthracene (BA), for their ability to cause liver growth...

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.;...

Algorithms for string matching with applications in molecular biology

Creator:: Holloway, James Lee
Abstract:: As the volume of genetic sequence data increases due to improved sequencing techniques and increased interest, the computational tools available to analyze the data are becoming inadequate. This thesis seeks to improve a few of the computational methods available to access and analyze data in the genetic sequence databases. The...

Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

Creator:: Kim, GilSoo
Abstract:: The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

The development of aminal radicals for the synthesis of nitrogen-rich natural products

Creator:: Schiedler, David A.
Abstract:: Organic compounds which contain one or more nitrogen atoms are especially important as they are disproportionately represented among biologically active molecules. As a result, significant effort has been focused on the development of methods for the synthesis of nitrogenous molecules. We identified the aminal as an under-explored functional group. Despite...

Total Synthesis of Goniomitine : Development of Aminal and α-Amino Radicals in the Synthesis of Nitrogen-Rich Natural Products

Creator:: Vellucci, Jessica K.
Abstract:: Aminal radical intermediates were generated by the method of radical translocation and reacted in C-C bond forming reactions with electronically deficient alkenes (Schiedler et al. Org. Lett. 2012, 14, 6092). Aminal radical intermediates can participate in inter- and intra-molecular reactions using both Bu3SnH and (TMS)₃SiH as hydride donors. Carbon–carbon bonds...
