    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.

    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.

    Development of pinene-derived N,P ligands and their utility in catalytic asymmetric hydrogenation2007In: Dalton Transactions, ISSN 1477-9226, E-ISSN 1477-9234, no 47, p. 5603-5610Article in journal (Refereed)
    Abstract [en]

    New diastereomeric N,P-ligands, derived from the natural product (+)--pinene, have been synthesized and evaluated in iridium-catalyzed asymmetric hydrogenation. The ligands are tetrahydroquinoline derivatives synthesized directly from commercially available -pinene utilizing resolution or recrystallization to separate diastereomers. In reduction of a range of different trisubstituted alkenes the catalysts express very different activities ranging from no activity to high activity. One of the catalysts gives good ee values for some substrates.
