Alkylation studies on Hagemann's ester: an approach to the synthesis of the trisporic acids

Creator:: Sung, Wing Lam
Abstract:: Sequential alkylation of Hagemann's ester with methyl and methallyl halides has been studied. Treatment of Hagemann's ester with methyl iodide and sodium ethoxide gave a mixture of 21 and 25 in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium t-butoxide afforded a mixture of 37 and...

Some synthetic efforts in small ring chemistry

Creator:: Lam, Luke Kwok Tung
Abstract:: Cyclopropylcyclobutene was prepared via the intermediate dicyclopropylcarbinyl carbene which was generated by the thermal decomposition of the sodium salt of dicyclopropylketone p-toluenesulfonylhydrazone. The successive thermal isomerization of cyclopropylcyclobutene to 2-cyclopropyl-1, 3-butadiene and to vinylcyclopentene was studied. Kinetic data were obtained for the cyclopropylcyclobutene to 2-cyclopropyl-1, 3-butadiene isomerization in the gas...

Investigation of Chain Extension Approaches for the Stereoselective Reagent-Controlled Synthesis of alpha-Heteroatom Substituted Alkyl Boronic Esters

Creator:: Barsamian, Adam L.
Abstract:: Two distinct strategies were explored for the enantioselective synthesis of α-heteroatom substituted alkyl boronic esters by stereoselective reagent-controlled homologation using transient chiral carbenoid reagents CHYMX (Y = heteroatom, X = nucleofuge, M = electrofuge). In the first case, a stereospecific reagent-controlled homologation (sStReCH) approach to α-alkoxyalkylboronates using α-metalated S,O- and...

Structural and magnetic investigation of In₂Fe₂₋ₓGaₓCuO₇

Creator:: Grajczyk, Rosa, Chan, Adam, Ramirez, A. P., and Subramanian, M. A.
Abstract:: The solid solution of In₂Fe₂₋ₓGaₓCuO₇ (space group P6₃/mmc) was synthesized and investigated through X-ray diffraction and magnetic susceptibility studies. Limited changes to the lattice parameters were observed as a result of the similar ionic radii for Fe³⁺ and Ga³⁺ in the trigonal bipyramidal (TBP) crystallographic site. An increase in the...

Investigation of the structural influence on the properties of functional inorganic oxides

Creator:: Laurita-Plankis, Geneva
Abstract:: While properties are extremely important from an application point of view, it is crucial to have a detailed understanding of the underlying structural influence. Once a concrete correlation between the structure and the observed property is established, rational design of novel materials with optimized properties can be realized. These optimized...

Investigation of mixed N,O-donor dipicolinamide derivative ligands for use in nuclear fuel separations

Creator:: Lapka, Joseph
Abstract:: In this work, three isomeric forms of N, N'-diethyl, N, N'-ditolyldipicolinamide (EtTDPA) were synthesized. The elements thorium through americium, which make up a significant portion of the actinides in used nuclear fuel (with the exception of curium), and two fission products, molybdenum and technetium, were tested for their ability to...

Computational Investigations of Transition Metal Catalyses and Amorphous Metal Oxides : Accelerating Scientific Discovery Through Automation

Creator:: Mustard, Thomas J. L.
Abstract:: Automation of computational chemistry, while only an engineering feat, has the potential to accelerating computational research be removing all by the science. The work in this thesis mainly discusses fundamental understanding of complex chemical systems. What is not obvious are the numerous tasks necessary for this fundamental understanding. Under the...

Effects of atmospheric pressure on line widths and spatial distributions of the transient atomic absorption signals of minor constituents in metal samples atomized by a dye laser microprobe

Creator:: Manabe, Ronald M.
Abstract:: Investigations of plasma production by a pulsed dye laser microprobe were made. Comparisons between a Q- switched and a pulsed dye laser system were made on the intensity of the continuum produced by atmospheric breakdown. The dye laser system was foundtominimize the production of the continuum which in turn allowed...

Femtosecond Stimulated Raman Studies of Excited State Structural Events

Creator:: Tang, Longteng
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is an ultrafast vibrational technique which allows rapid collection of Raman spectra with simultaneously high temporal and spectral resolution. With the recent development of FSRS methodology, three FSRS techniques (conventional, tunable, and anti-Stokes) have been implemented in our laboratory to dissect the excited state structural...

Scaffold reactivity and large scale Synthesis of organocatalyzed Yamada-Otani Condensation product and investigation of the synthesis and properties of axially chiral 8,8'-biquinolyls and 8-(naphtha-1-yl)quinolines

Creator:: Banerjee, Somdev
Abstract:: In Part I, (4S,5R)-4,5-dimethyl-4-phenylcyclohex-2-enone (19a) was prepared in 73% yield with high enantio- and diastereo-selectivity (er > 98:2, dr > 20:1) on a multigram scale by a Yamada-Otani condensation between (E)-pent-3-en-2-one and 2-phenylpropanal catalyzed by a sulfonimide derivative of (S)-proline (18, HuaCat®). Synthetically useful transformations of the cyclohexenone product 19a...
