  • 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.

  • Methods of preparing ?,?-unsaturated or ?-halo ketones and aldehydes
    Patent number: 9796653
    Abstract: Copper(II) bromide mediated oxidation of acylated enol and use of the reaction in the synthesis of ?,?-unsaturated or ?-bromo ketones or aldehydes are disclosed. The method provides an efficient and practical process for manufacturing dehydrohedione (DHH) and many other versatile ?,?-unsaturated or ?-bromo ketones or aldehydes in large scales to avoid using precious metal compounds.

  • METHOD FOR SELECTIVE PALLADIUM-CATALYZED TELOMERIZATION OF SUBSTITUTED DIENES
    Publication number: 20170275235
    Abstract: A method for the selective synthesis of a tail-to-head, or a head-to-head, or a tail-to-tail telomer from an unsymmetrical diene by polymerizing the diene in the presence of [Pd(C3H5)COD]BF4 and dicyclohexyl-[1-(2,4,6-trimethylphenyl)imidazol-2-yl]phosphane, Pd(OAc)2 and triphenylphosphine, or [Pd(C3H5)COD]BF4 and tris(2,4-di-tert-butylphenyl)phosphite in combination with a polar protic alcohol, an acidic polar protic alcohol, a polar aprotic ether, or a non-polar aprotic hydrocarbon is provided.
