Chiral synthesis of alcohols via asymmetric epoxidation

Creator:: Engebrecht, Jeffrey Ronald
Abstract:: Enantioselective epoxidation of crotyl alcohol, followed by a cuprate mediated methylation, gave a 1:1 mixture of (2S) -3- methyl -1,2- butanediol and (2R,3S)-2-methy1-1,3- butanediol. The latter was separated as its 2,4,6-trimethylbenzenesulfonate derivative and converted via the iodide to the corresponding phosphonium salt. The separated butanediol derivatives were independently transformed to...

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...

High-resolution X-ray photoelectron spectroscopy of CO₂ and other small molecules

Creator:: Hahne, Jeffrey A.
Abstract:: The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...

A critical comparison of methods for the determination of phytoplankton chlorophyll

Creator:: Salinas, John T.
Abstract:: The concentration of chlorophyll in natural bodies of water is commonly determined as a means to rapidly estimate the phytoplankton biomass. The literature gives numerous warnings, however, as to the problems involved with accurately determining chlorophyll concentrations. The author's work at Crater Lake, Oregon enticed him to explore critically the...

Synthesis of some bicyclo[6.1.0] - nonane derivatives

Creator:: Wall, Robert Gene
Abstract:: Bicyclo [6.1.0] non-4-ene was prepared by two routes; (1) reaction of cis-cis-1, 5-cycloöctadiene with methylene iodide and zinc-copper couple, (2) sodium-methanol reduction of 9, 9-dibromobicyclo-[6.1.0] non-4-ene. The bicyclononene was characterized by its infrared spectrum, nuclear magnetic resonance spectrum and common physical properties. The olefin was hydrogenated to bicyclo [6.1.0] -...

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...

Using Computational Methods to Elucidate Reaction Mechanisms for Copper Catalyzed Reactions

Creator:: Caspary, Katherine E.
Abstract:: In this report, two studies are presented that utilize computations to predict and elucidate the reaction mechanisms of two different copper catalyzed reactions. Each study provides insight into the various chemical transformations, as well as the how and why behind regioselectivity and isotopic selectivity. The importance of this research is...
