Jamison Tuttle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hydride reduction of alpha, beta-unsaturated carbonyl compounds using chiral organic catalysts
    Publication number: 20080125310
    Abstract: Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an ?,?-unsaturated carbonyl compound. The ?,?-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of ?,?-unsaturated carbonyl compounds.
    Type: Application
    Filed: December 19, 2007
    Publication date: May 29, 2008
    Applicant: California Institute of Technology
    Inventors: David MacMillan, Stephane Ouellet, Jamison Tuttle
