The isolation and structure of leptosphaerin : a metabolite of the marine ascomycete, Leptosphaeria oraemaris (Linder) and A synthesis of the marine toxin, 9-isocyanopupukeanane

Creator:: Schiehser, Guy Alan
Abstract:: The ethyl acetate extract of the culture filtrate of the marine Ascomycete, Leptosphaeria oraemaris (Linder) yielded a novel metabolite designated by the common name leptosphaerin. An x-ray crystallographic structure analysis was disproved by the synthesis of 3-acetoxy-S-(1,2-dihydroxyethyl)- 3-pyrrolin-2-one 1, starting with N,N-dibenzylhydroxylamine 47 and D-mannitol 44. Oxidation of 47 followed...

Slow processes in gas-solid chromatography

Creator:: Burns, Walter Frederick
Abstract:: Gas-solid chromatography often has asymmetrical elution peaks. This is attributed to nonlinear isotherms, multi-energy adsorption sites, and slow processes. This study utilized a stopflow gas chromatograph with various NaOH and NaCl modified aluminas as adsorbents and methane as adsorbate to determine the influence of surface area and pore volume distribution...

Proton-neutron-hole states in antimony isotopes populated in the beta decay of ¹²⁸SN and ¹³⁰SN

Creator:: Nunnelley, Lewis Lee
Abstract:: ¹³⁰ Sn and ¹²⁸Sn were separated from mixed fission products. The decay of these isotopes were studied with Ge(Li), LEPS, and plastic scintillator detector systems in single and two parameter coincidence modes. The decay scheme constructed for ¹²⁸Sn decay has levels at 0.0 (5+), 45.7 (4+), 77.8 (3+), 152.9 (2+),...

Atmospheric trace element abundances associated with slash burning

Creator:: Ungerer, Carl Andre
Abstract:: The atmospheric trace element abundances associated with slash burning have been measured by instrumental neutron activation analysis (INAA). On site ground level samples were collected during the slash burning season using high volume samplers and a cascade impactor. In addition to the air samples, soil, wood and ashed wood samples...

The synthesis of substituted 1, 8-naphthyridines by the Doebner reaction

Creator:: Samalapa, Prasit
Abstract:: The possibility of synthesizing 1, 8-naphthyridines by the Doebner reaction has appeared in many reports. The method involves the introduction of electron releasing groups in the 6-position of 2-amino pyridine to activate the C-3 position. Previously Lewis used 6-methyl-2-amino pyridine with benzaldehyde and pyruvic acid, in an attempt to prepare...
