  • Chemical process of preparing dehydrohedione
    Patent number: 11198667
    Abstract: Disclosed is a chemical process of preparing dehydrohedione from Hedione via ?-chlorination and elimination steps. The process can be conducted in a one-pot process or in a continuous reactor system. Accordingly, a simple and cost effective process of preparing cis-Hedione enriched products is developed through reduction of dehydrohedione in the presence of a chiral catalyst system.
    Type: Grant
    Filed: March 30, 2018
    Date of Patent: December 14, 2021
    Assignee: International Flavors & Fragrances Inc.

  • Preparation of cyclic allylic nitro compounds
    Patent number: 10717701
    Abstract: Amine-catalyzed formation of cyclic allylic nitro compounds via nitro-aldol reaction is disclosed. A greener solvent and a cheaper, more robust catalyst than in previous reports are used in the nitro-aldol reaction. After screening a range of catalysts the reaction is developed as a selective method of synthesis of ?-dehydroherbac and the scope is demonstrated with a small collection of additional substrates.
