The present invention relates to novel methine dyes, methods for the preparation thereof and use thereof for dyeing plastics, especially polyamides, so as to obtain yellow to orange colourings with improved light fastness and improved thermal stability.
Direct enantioselective hydrogenation of unsaturated compounds to generate chiral three-dimensional motifs is one of the most straightforward and important approaches in synthetic chemistry. We realized the Ru(II)-NHC-catalyzed asymmetrichydrogenation of 2-quinolones under mild reaction conditions. Alkyl-, aryl- and halogen-substituted optically active dihydro-2-quinolones were obtained in high yields
A direct, one-pot and regioselective access to N-alkyl- and N-aryl-substituted 2-pyridones is described from readily available β-keto amides and either primary or secondary propargylic alcohols. This approach involves the combination of two different cooperativehomogeneous and heterogeneous catalytic systems based on a transition metal oxide and a supported organocatalyst, respectively.

The present invention provides compositions of matter, kits and methods for their use in the treatment of MAP kinase-related conditions and/or HMG-CoA reductase-related conditions. In particular, the invention provides compositions for treating inflammatory and/or cardiovascular conditions in an animal subject by inhibiting p38α MAP kinase and/or HMG-CoA reductase, as well as providing formulations and modes of administering such compositions. The invention further provides methods for the rational design of inhibitors of MAP kinase, HMG-CoA reductase, or both for use in the practice of the present invention.
