Studies towards the total syntheses of (+)-phomactins A, D and G

Creator:: Schwartz, Keith D.
Abstract:: Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....

Part I: Total Syntheses of Mandelalide A and Isomandelalide A. Part II: Role of π-Stacking on Sharpless Dihydroxylation of cis-Enynes: Synthetic Studies Toward All Carbon Macrocyclic Mandelalide B

Creator:: Ghosh, Ankan
Abstract:: Part I of this dissertation includes the chronological synthetic background of mandelalide A as well as the synthesis of the C1-C14 glycosylated southern subunit of mandelalide. A key aspect of the synthesis includes a novel silver-catalyzed cyclization (AgCC) of a propargylic benzoate to construct the substituted cis-pyran ring system present...

A reinvestigation of the molecular structure of cyclohexane-1,4-dione by electron diffraction

Creator:: Johnson, Robert David
Abstract:: We have investigated the gaseous structure of cyclohexane- 1,4-dione via electron diffraction. The large amplitude motion, as suggested from spectroscopic, dipole moment and earlier electron diffraction data was studied. The structure was refined in two types of models: a single "distorted boat" conformer, and a model comprised of a superposition...

Evidence for a soluble intermediate of oxidative phosphorylation isolated from cabbage mitochondria

Creator:: Johnson, Morris Alfred
Abstract:: An intermediate of oxidative phosphorylation was apparently solubilized from cabbage mitochondria. The method of solubilization used primarily was extraction of a mitochondrial acetone powder with 0.1 M glycylglycine, pH 7.4, at 4° C. The intermediate betrayed its presence by causing the transfer of Pi³² to ADP with the resultant formation...

Tracking Excited State Proton Transfer and Inhibition with Ultrafast Raman and Transient Absorption Spectroscopy

Creator:: Oscar, Breland G.
Abstract:: In this dissertation, excited state proton transfer (ESPT) and its inhibition in solution and protein environments are revealed using both femtosecond transient absorption (fs-TA) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS). Using a tunable Raman pump to enhance transient vibrational features of the photoacidic chromophore HPTS in methanol and methanol...
