  • CONVERGENT SYNTHESIS OF RENIN INHIBITORS AND INTERMEDIATES USEFUL THEREIN
    Publication number: 20130310577
    Abstract: Described is a method for the preparation of renin inhibitors such as aliskiren, and intermediates useful therein. The method introduces a nitrogen-containing intermediate such as a lactone of formula (8). with R4 being a branched C3-6 alkyl. In the preparation of the lactone, or related intermediates, a desired stereochemical configuration can be controlled by starting from a chiral aldehyde satisfying formula (10).
    Type: Application
    Filed: July 11, 2013
    Publication date: November 21, 2013
    Applicant: DSM IP ASSETS B.V.
    Inventors: Ben DE LANGE, Anna Maria Cornelia Francisca CASTELIJNS, Johannes Gerardus DE VRIES, Andreas Hendrikus Maria DE VRIES, Jeroen Antonius Franciscus BOOGERS

  • Preparation of a saturated aldehyde
    Patent number: 8088954
    Abstract: The invention relates to a compound according to Formula (IX) and salts thereof, wherein R1, R2 and R5 are each independently selected from H and hydrocarbon moieties, which hydrocarbon moieties optionally comprise one or more heteroatoms, and which hydrocarbons optionally comprise substituents, or when the compound according to formula (IX) is a salt, R1 and/or R2 may be a cation, R3, and R4 each independently selected from hydrocarbon moieties, which hydrocarbon moieties optionally comprise one or more heteroatoms, and which hydrocarbons optionally comprise substituents, and wherein any two of R1, R2, R3, R4 and R5 are optionally linked together to form a ring structure. The invention further relates to the preparation of such a compound and to the use of such a compound for preparing a pharmaceutical compound, an agrochemical compound, an intermediate for a pharmaceutical compound or an intermediate for an agrochemical compound.
