Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...

A stereochemically controlled approach to the morphine alkaloids: racemization of 8,9-benzo-4,5-dihydro-6,7-pyrido[4,3-d] oxanin-3(2H)-ones

Creator:: Runyan, Mark T.
Abstract:: A method for the control of absolute stereochemistry in morphine syntheses has been demonstrated by the resolution and efficient racemization of the advanced morphine precursor , 9-methoxy-3-methyl-5,6-dihydro-3H-benzofuro[3,2-e]isoquinoline- 7(7aH)-one, I. This was accomplished by the facile coversion of optically resolved I to its ring opened form, 5,6,7,8-tetrahydro-10-methoxy-3-methyl-7-oxo[1]benzoxonino[ 6,7-c]pyridinium tosylate, II, (Equation...

Part I : development and application of an arsenic speciation technique using ion-exchange solid phase extraction coupled with GFAAS ; Part II : investigation of zinc amalgam as a reductant

Creator:: Bos, Mark C.
Abstract:: Two related techniques, based upon ion-exchange solid phase extraction, have been developed for the determination of arsenic speciation. The inorganic arsenic species arsenite (As(III)) and arsenate (As(V)) are separated by anion-exchange and detected with graphite furnace atomic absorption spectrophotometry (GFAAS) with a nickel matrix modifier. The first separation technique, which...

Hydrophobicity, Anion Exchange, and Phytoaccumulation of Per- and Polyfluoroalkyl Substances (PFAS): Retention and Remediation

Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...
