    Microwave-Assisted Asymmetric Intermolecular Heck Reaction using Phosphine-Thiazole Ligands2007In: Advanced Synthesis and Catalysis, ISSN 1615-4150, E-ISSN 1615-4169, Vol. 349, no 7-18, p. 2595-2602Article in journal (Refereed)
    Abstract [en]

    A series of new phosphine-thiazole compounds has been synthesized and used as efficient ligands in the palladium-catalyzed asymmetric intermolecular Heck coupling of 2,3-dihydrofuran with aryl triflates and cyclohexenyl triflate. Microwave heating was used to accelerate the reactions and gave complete conversions in as little as one hour. Products were obtained with good to excellent enantioselectivities.

    Asymmetric hydrogenation of tri-substituted alkenes with Ir-NHC-thiazole complexes2006In: Tetrahedron Letters, ISSN 0040-4039, E-ISSN 1359-8562, Vol. 47, no 42, p. 7477-7480Article in journal (Refereed)
    Abstract [en]

    An efficient chiral N-heterocyclic carbene ligand for the Ir-catalyzed asymmetric hydrogenation of largely unfunctionalized tri-substituted olefins has been developed. The Ir-NHC-thiazole catalyst is able to reduce a large variety of substrates with excellent conversions and good enantioselectivities with ee's ranging from 34% to 90%, depending on the geometry around the double bond of the substrates.

    New ligands for the RuCp*-diamine catalysed asymmetric hydrogenation of aryl ketones2007In: Comptes rendus. Chimie, ISSN 1631-0748, E-ISSN 1878-1543, Vol. 10, no 3, p. 213-219Article in journal (Refereed)
    Abstract [en]

    New chiral diamine ligands have been synthesized and evaluated in the asymmetric Ru-catalyzed hydrogenation of prochiral aryl ketones. All catalysts showed good conversions with observed enantioselectivities ranging from moderate to good.
