  • Studies toward the total synthesis of alkaloids : nagelamide A and D, agelastatin D, dragmacidin A-C, salacin and almazoles

    Creator:
    Tonsiengsom, Sorasaree
    Abstract:
    Studies toward the total syntheses of highly potent cytotoxic alkaloids including the bromopyrrole alkaloids and indole alkaloids were conducted and are described. Studies carried out in the course of this dissertation consist of five total syntheses of natural products that include bromopyrrole alkaloids nagelamide A, D and agelastatin D as...

  • Approaches to the total synthesis of verrucarol

    Creator:
    Hill, David E. (David Edwin) 1954-
    Abstract:
    Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...

  • The biosynthesis of terpenes in Pelargonium graveolens

    Creator:
    Allison, Robert David
    Abstract:
    Pelargonium graveolens Ait., rose geranium, contains several oxygenated monoterpenes, most of which are related to each other structurally. In this work, the metabolism and interconversions of these terpenes was investigated. A chromatographic analysis of geranium oil was performed initially for the purposes of identifying the terpenes and determining which chromatographic...

  • Steroid dialkylcarbene reactions

    Creator:
    Dixon, Dale David
    Abstract:
    Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

    Creator:
    Schwartz, Keith D.
    Abstract:
    Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....

  • Enantioselective Total Syntheses of Quinolizidine Lycopodium Alkaloid Cermizine D and Cytotoxic Marine Macrolide Mandelalide A

    Creator:
    Veerasamy, Nagarathanam
    Abstract:
    The enantioselective total synthesis of quinolizidine-containing natural product cermizine D and formal syntheses of senepodine G and cermizine C has been achieved. These natural products are members of the lycopodium alkaloids, which have attracted significant attention due to their exciting biological activities and the diverse structural scaffolds. Key steps in...

    Abstract:
    Studies towards the total synthesis of (-)-gymnodimine (1), a marine neurotoxin with a unique molecular architecture and pronounced biological activity, are described. These studies resulted in a convergent approach to the advanced intermediate 315, containing the C3-C32 section of 1. Two synthetic routes were developed to construct the tetrahydrofuran subunit...

  • Studying fusion reactions for effect of PCN on heavy nucleus formation and for nuclear structure effects

    Creator:
    Naik, Radhika
    Abstract:
    The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...
