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

    Toh, Ophilia Ndi2008

    … 1, 3-diploar cycloaddition reactions with dipolarophiles to form isoxazolines and/or its dimers. This procedure represents a novel, safe general method for the one-step generation of fulminic acid, which complements existing potentially explosive protocols.</p>

  3. The progress towards the total synthesis of (ent)-MPC1001

    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. …
