STUDIES ON ENANTIOSELECTIVE DESYMMETRIZING ALKYNE HYDROSILYLATION
(2021-08-12)This research focuses on the design and synthesis of enantioselective desymmetrizing α-hydrosilylation of propargyl alcohols to provide α-hydroxy (E)-vinylsilanes. Transition metal-catalyzed, regio-and stereoselective ... -
Studies On Field Stabilization Methods To Prevent Surficial Slope Failures Of Earth Fill Dams
(Civil & Environmental Engineering, 2009-09-16)Surficial failures are occurring frequently on the slopes of earthfill dams which are predominantly rainfall induced. Desiccation cracks form on the slope surface during dry environment which accelerates infiltration during ... -
Studies On Reductive Horner-Wadsworth-Emmons Olefination Using Mixed Silyl Acetals
Homologation of esters to α,β-unsaturated esters is a useful transformation in organic synthesis. We have developed a new approach for the Ir-catalyzed reductive Horner-Wadsworth-Emmons olefination of esters; a one-pot ... -
Studies On Volume Change Movements In High PI Clays For Better Design Of Low Volume Pavements
(Civil & Environmental Engineering, 2008-09-17)Numerous low- to medium-volume roads such as Farm Market (FM) roads constructed on expansive clay subgrades, especially in the eastern and central Texas, encounter severe pavement cracking and premature loss of serviceability. ... -

(2024-01-02)**Please note that the full text is embargoed until 02/01/2026** This thesis documents progress toward a total synthesis of the marine natural product palau'amine, a stereochemically dense hexacyclic pyrrole-imidazole ... -
Studies Toward The Enantioselective Total Synthesis Of The Martinella Alkaloids
(Chemistry & Biochemistry, 2007-08-23)This dissertation consists of two parts. The first part describes the enantioselective total synthesis of martinellic acid. The Martinella alkaloids have attracted considerable attention in the synthetic community over the ... -
Studies Towards Bioactive Imidazoles
(Chemistry & Biochemistry, 2008-04-22)The work presented in this thesis focuses on the development of an enantioselective and practical route form the total synthesis of villagorgin via haplosleridamine imidazole alkaloid containing β- carboline moiety by ... -
STUDIES TOWARDS THE TOTAL SYNTHESIS OF IMIDAZOLE-CONTAINING NATURAL PRODUCTS
(2018-09-11)Nature has inspired man in all aspects of life, chemistry included. The first antibiotic ever discovered came from nature, and since then, chemists have been probing nature for insights to guide drug discovery and development. ... -
Studies Towards The Total Synthesis Of Haploscleridamine And Ceratinadin B
In Chapter 1, we discuss the synthesis of haploscleridamine. Haploscleridamine is a novel tryptamine-derived alkaloid isolated from a sponge of the order Haplosclerida. This alkaloid inhibits cathepsin K, a cysteine protease, ... -
A Study Of Diamond Nanoparticles
(Materials Science & Engineering, 2011-07-14)Diamond nanoparticles grown previously by Hot Filament Assisted Chemical Vapor Deposition have been characterized by utilizing Atomic Force Microscopy, Scanning Electron Microscopy, Raman Spectroscopy and X Ray Diffraction. ... -
