  1. Synthesis Towards Fulminic Acid and Its Derivatives in 1, 3-Dipolar Cycloaddition Reactions.

    Toh, Ophilia Ndi2008

    <p>A new approach to fulminic acid cycloadditions has been developed. At reduced temperatures, fulminic acid is generated <em>in situ</em> and undergoes 1, 3-diploar cycloaddition reactions with dipolarophiles to form isoxazolines and/or its dimers. This procedure represents a novel, safe general …

    Schuber, Paul, author, Williams, Robert M., advisor, Crans, Debbie, committee member, Finke, Richard, committee member, McNaughton, Brian, committee member, Slayden, Richard, committee memberColorado State University. Libraries2011

    … with the development of a novel asymmetric [1-3]-dipolar cycloaddition utilizing a vinyl silane and a chiral lactone template. The mechanism of the cycloaddition was investigated and the cyclized product can be elaborated in 6 steps to the A-B-C ring system of the MPC family of natural products. …

  3. IMPROVED SYNTHESIS OF 3-ARYL-ISOXAZOLES AS INTERMEDIATES FOR NOVEL G-QUADRUPLEX BINDING ANTI-TUMOR AGENTS

    Weaver, Matthew Jacob

    … fused aromatic rings using the nitrile oxide cycloaddition (NOC) revealed that modification of the method of Bode, Hachisu, Matsuura and Suzuki (BHMS), was far superior to that of the enamine method. Utilization of either triethyl amine as a base or sodium enolates of diketone, ketoester and …

  7. Ex-Chiral-Pool-Synthese von 5-Aminopiperidylessigsäuren über eine Tandem-Wittig-1,3-dipolare Cycloaddition

    Güthlein, MarkusUniversität Würzburg

    Ziel dieser Arbeit war es die Tandem-Wittig-1,3-dipolare Cycloaddition auf a-Hydroxyurethanderivate zu übertragen und so chirale, nichtracemische b-Amino-piperidylacetatderivaten in möglichst hoher Diastereomerenreinheit darzustellen. Diese Aminopiperidinderivate sollten mit …
