Stereoselective synthesis & application of enantioenriched main group α-haloalkyl organometal reagents

Creator:: Emerson, Christopher R.
Abstract:: Sulfoxide-ligand exchange (SLE) and asymmetric halogen-metal exchange (AHME) processes were separately examined for the enantioselective synthesis of functionalized alpha-haloalkylmetal (carbenoid) reagents. Carbenoids derived from SLE were used to effect stereospecific reagent-controlled homologation (StReCH) of boronic esters and those generated via AHME were engaged in Darzens-type chemistry with aldehydes. Abstract for...

Rationalization and innovative design of asymmetric organocatalysts through computational investigation

Creator:: Johnston, Ryne Connell
Abstract:: My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...

Stereospecific Synthesis of Stereotriad Motifs and Alkenes Using Enantioenriched sp³-Hybridized Carbenoids

Creator:: Xun, Sun
Abstract:: Enantioenriched sp³-hybridized carbenoid reagents CR1R2MX (X = nucleofuge, M = electrofuge) of different types were investigated for the synthesis of polysubstituted alkyl chains by iterative stereospecific reagent-controlled homologation (StReCH) and for the stereospecific connective synthesis of alkenes by eliminative cross-coupling. In the first part, putative enantioenriched α-chloroalkyllithiums (CHRLiCl) were employed...

Nutritional muscular dystrophy production and pectoral muscle 5'-nucleotidase activity in the chick

Creator:: Roffler, Sheila Ann
Abstract:: In an attempt to find a laboratory species which develops an experimental myopathy similar to white muscle disease (WMD) in lambs, comparative studies of nutritional muscular dystrophy of chicks were initiated. This condition was grossly visible as white striations running parallel with the fibers of the pectoral muscles and was...

Precursor-directed Biosynthesis and Total Synthesis of Aniline-containing Natural Products from the Endophytic Fungus Chalara sp. 6661

Creator:: Khoshbakht, Mahsa
Abstract:: Chalaniline A, an unusual xanthone-like aminofulvene with modest cytotoxicity, and chalaniline B [1-anilino-2,8-dihydroxy-3-(hydroxymethyl)xanthone], an antibacterial aminoxanthone, were previously isolated by Loesgen and coworkers from vorinostat-treated Chalara sp. 6661. Of note, the anilino moiety found within both chalaniline structures originates from biotransformation of the HDAC inhibitor vorinostat (SAHA, suberanilohydroxamic acid) by...

Metabolism of copper in blood and liver as influenced by species and diet

Creator:: Milne, David Bayard
Abstract:: Copper in blood and liver can be divided into several fractions. Copper in blood is about evenly divided between erythrocytes and plasma. Normal concentrations for most species range between one and two parts per million. Plasma copper is mainly a copper protein, ceruloplasmin and a loosely bound form, reacting directly...

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...
