Bioprospecting the Chemical Diversity of Plant-associated Fungi

Creator:: González-Montiel, Gisela Abigail
Abstract:: Fungi have long been used for discovery of new chemical scaffolds. In the clinical setting, the fungal natural products penicillin, statins, and cyclosporine have revolutionized medicine to treat diseases and infections. In the environment, fungal natural products have been used as herbicides, fungicides, and insecticides to protect crops, livestock, and...

A study of the chemistry of diisopropyl-, cyclopropylisopropyl-, and dicyclopropylcarbene

Creator:: Wuerch, Stephen E.
Abstract:: The effect of the conjugation with cyclopropyl rings on the activation parameters for the formation of carbenes from the corresponding diazo compounds was investigated using diisopropylcarbene (46), cyclopropyl-isopropylcarbene (47), and dicyclopropylcarbene (48). Each of these three carbenes was generated by the thermolysis of the parent benzenesulfonylhydrazone potassium salts using DMSO...

Synthesis and oligomerization of y,4-Diamino-2-oxo-1(2H)-pyrimidinepentanoic acid

Creator:: Nelson, Jeffrey Stephen
Abstract:: Described herein is the synthesis of an uncharged stereoregular oligonucleotide analog consisting of cytosine bases linked at specific intervals to a polyamide backbone derived from (L)-glutamic acid. Preparation of this analog entailed borane reduction of (L)- pyroglutamic acid to give optically pure lactam alcohol 9. Tosylation and alkylation with cytosine...

Classification of stationary liquids in gas chromatography by infrared spectrophotometry

Creator:: De Briceno, Maria Betania Orduz
Abstract:: A classification of stationary liquids by infrared spectroscopy to evaluate the polarity was made using the solvent effect technique. The infrared C-Cl absorption frequency shift was measured for solutions of 1-chlorohexane dissolved in each stationary phase. These frequency shifts were correlated to the relative retention times of 1-octene/n-octane, trans-2-octene/n-octane and...

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...

Classification of stationary phases in gas chromatography

Creator:: Chong, Elee Elizabeth
Abstract:: Ultraviolet spectroscopy and dispersive solubility parameters correlated to the ratios of retention times have proven valuable in classification of gas chromatography stationary phases by the donor-acceptor properties. Iodine was directly dissolved into stationary phases and the absorption frequency shift of complexes was correlated with the carbon tetrachloride/chloroform retention ratio on...

A quadratic programming routine for the statistical analysis of gas chromatographic data

Creator:: Elliott, Stanley Claud, Jr
Abstract:: A quadratic programming method was developed for the statistical analysis of gas chromatographic data. The method was applied to three types of flavor extracts, peppermint, hops and brewed tea. The brewed tea data had to be abandoned because of the singularity of its coveriance matrix. In all cases tried the...
