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...

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...

GaAs(100) surface chemistry : interactions with molecular chlorine and sulfur compounds

Creator:: Mokler, Scott M.
Abstract:: An important aspect in device technology is the processing of GaAs to produce highly-resolved etch patterns on the substrate. This is done typically on the GaAs(100) surface. Recently, a number of methods, all using chlorinated vapor reactants, have been applied to fabrication of GaAs devices. In spite of these technological...

Novel ternary graphite intercalation compounds of alkali metal cations and amines

Creator:: Maluangont, Tosapol
Abstract:: Novel ternary graphite intercalation compounds (GICs) of alkali metal cations and a wide variety of amines have been synthesized by one-pot chemical syntheses. Alkali metals studied includes Li, Na and K. The families of amines employed are nalkylamines, branched alkylamines, and different structural isomers of diamines and polyamines. Intragallery structures...

Studies towards the total synthesis of (-)-kendomycin

Creator:: Smits, Helmars
Abstract:: Studies towards the total synthesis of (−)-kendomycin (1), a bacterial metabolite with a unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediate 208, containing all of the carbon atoms of 1. A Dötz annulation between alkyne 122 and novel chromium carbenoid...

Composition and sources of organic tracers in aerosol particles of industrial central India

Creator:: Giri, Basant, Patel, Khageshwar S., Jaiswal, Nitin K., Sharma, Saroj, Ambade, Balram, Wang, Wentao, Simonich, Staci L. Massey, and Simoneit, Bernd R. T.
Abstract:: Organic aerosols are important atmospheric components, and their formation and sources represent important aspects of urban air quality and health effects. Asia, including India, is the largest global source of aerosol particles due to regional natural advection (e.g. desert and soil dust) and anthropogenic activities (e.g. emissions from traffic, industry...

Total synthesis of (-)-7-epicylindrospermopsin

Creator:: Hansen, Joshua D.
Abstract:: The first asymmetric synthesis of (-)-7-epicylindrospermopsin via intramolecular nitrone cycloaddition is described. The synthesis utilized a convergent approach to prepare the cycloaddition precursor 176, which was assembled by condensation of hydroxylamine 175 with aldehyde 145. Hydroxylamine 175 was synthesized from ethylene glycol (166) in seven steps. Aldehyde 145 was completed...
