  • Patent number: 7884223
    Abstract: The invention relates to an enantiomerically enriched chiral compound comprising a transition metal M, which comprises four, five or six coordinating groups of which at least one pair is linked together to form a bidentate ligand, in which M is directly bound via one single ?-bond to a carbon atom of an optionally substituted and/or optionally fused (hetero)aromatic ring of said bidentate ligand and in which M is directly bound to a nitrogen atom of a primary or secondary amino group of said bidentate ligand, thereby forming a metallacycle between said bidentate ligand and the metal M, said metal M being selected from the metals of groups 8 and 9 of the Periodic Table of the Elements, in particular iron, ruthenium, osmium, cobalt, rhodium, or iridium. The chiral compound can be used as a catalyst, preferably in an asymmetric transfer hydrogenation process.

  • Publication number: 20110008852
    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).

  • Publication number: 20040077872
    Abstract: The invention relates to a process for carrying out a homogeneously catalyzed C—C coupling reaction between an optionally substituted (hetero)aromatic bromide compound and a second reactant, which is chosen from the group of olefins in which at least one of the substituents on the olefinic sp2 carbon atoms is a hydrogen atom, and the group of organoboron compounds with the formula Ar—B(OR1)—OR2, where Ar stands for an optionally substituted (hetero)aryl group and R1 and R2 each independently represent H or an alkyl group or, together with the O-atoms to which they are bound and the B-atom, form a ring with 2-5 C-atoms, in the presence of an aprotic dipolar solvent and a base, a palladium salt without a ligand being used as palladium catalyst and the reaction being carried out at a ratio between the quantity of palladium present in the palladium salt and the optionally substituted (hetero)aromatic bromine compound of between 0.00001 and 0.1 mol %, preferably between 0.01 and 0.1 mol %.
