Photochemistry of 6-alkenyl-2-cyclohexenones : synthetic studies towards precursors of ryanodol

Creator:: Wang, Bingbing
Abstract:: Regiochemistry of intramolecular [2+2] photocycloadditions of oxygenated 6-alkenyl-3-alkoxy-2-cyclohexenones is studied. Application of this methodology to construct a key intermediate [3.3.2] bicyclic skeleton of ryanodol is described as well. Irradiation of (3-butenyl)compounds 3, 11, 14 and of (4-pentenyl)compound 6 afforded exclusively the linear photoadducts 4, 12, 15 and 7 respectively. Irradiation...

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....

Studies of the biosynthesis of Sarubicin A

Creator:: Eisenberg, Rodney L.
Abstract:: Early studies on the biosynthesis of Sarubicin A, 1, had suggested the intermediacy of the novel aromatic amino acid 6-hydroxyanthranilic acid, 17. To investigate the biosynthetic steps beyond 17, [¹³C-¹⁵N carboxamide] 6-hydroxyanthranilamide, 27a, was synthesized, and fed to fermentations of Streptomyces helicus. Incorporation of 27a into 1 provided suggestive evidence...

Fate and transport of the surfactant linear alkylbenzenesulfonate in a sewage-contaminated aquifer

Creator:: Krueger, Carolyn J.
Abstract:: Linear alkylbenzenesulfonate (LAS) is the most widely used anionic surfactant in commercial detergent formulations. The environmental fate of LAS is of interest because of its disposal to wastewater treatment facilities and subsequent occurrence as a micropollutant in surface waters and groundwater. While LAS fate in wastewater treatment systems and surface...

Studies of glow discharge oscillations and jet-enhanced cathodic sputtering

Creator:: Zhu, Zhubiao
Abstract:: Three aspects of glow discharges have been studied: glow discharge oscillations, sputtering, and coupling between cathode and anode regions the two most important regions in a glow discharge. Cathode and anode processes are tightly coupled by electron and ion coupling effects. Both electron and ion coupling effects were observed by...

GaAs(100) surface chemistry : interactions with molecular chlorine and sulfur compounds

Creator:: Mokler, Scott M.
Abstract:: An important aspect in device technology is the processing of GaAs to produce highly-resolved etch patterns on the substrate. This is done typically on the GaAs(100) surface. Recently, a number of methods, all using chlorinated vapor reactants, have been applied to fabrication of GaAs devices. In spite of these technological...

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...

Fiber optic sensors and spectrometry for the detection of volatile gem-polyhalogenated hydrocarbons

Creator:: Louch, Jeff
Abstract:: A fiber optic fluorometer utilizing a double-fiber optic probe was constructed. The absolute fluorescence signal and effective collection efficiency are approximately one fifth those of typical cuvette fluorometers and agree with those predicted by theory. A quinine sulfate calibration curve shows linearity from a detection limit of 10 pg/mL to...
