    摘要: Provided is an industrially advantageous method for producing optically active alcohols in high yields from ketones of various structures by using an inexpensive chiral catalyst. The method of the present invention for producing optically active alcohols comprises reducing a ketone in the presence of an iridium(III) complex having a chiral prolinamide compound as a ligand. The ketone is preferably a compound represented by formula [I]:

    (wherein R 1 and R 2 are different from each other, and each represent an optionally substituted straight or branched alkyl group, an optionally substituted cycloalkyl group, an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted aralkyl group, an optionally substituted heteroarylalkyl group, an optionally substituted alkenyl group or an optionally substituted alkynyl group, and
    R 1 and R 2 may be bound to each other at any appropriate position to form a ring, the ring optionally containing one or more atoms which may be the same or different and are selected from an oxygen atom, an optionally substituted nitrogen atom and a sulfur atom, and optionally being condensed with an aromatic or hetero-aromatic ring).

    摘要: Improved methods for the recovery of xanthophylls from corn gluten meal are provided. More specifically, methods for the recovery of xanthophylls from corn gluten whereby relatively dry corn gluten is extracted with an organic alcohol followed by a saponification reaction to convert xanthophyll esters to xanthophylls is described. Also described are methods for the recovery of xanthophylls from corn gluten meal whereby relatively dry corn gluten meal is extracted with a first solvent containing an antioxidant and the resulting extract is, optionally, purified. Using these methods, xanthophylls can be recovered from corn gluten meal in higher yields, at greater efficiencies, and in higher purity as to compared to prior art methods. Moreover, the xanthophyll products recovered in these methods are ideally suited for use in food products and in pharmaceuticals. These materials are especially suited for use in poultry feeds to provide the desired, healthy yellow color or hue in broiler and egg yolks.
