CATALYST FOR ASYMMETRIC HYDROGENATION AND METHOD FOR MANUFACTURING OPTICALLY ACTIVE CARBONYL COMPOUND USING THE SAME
摘要:
The present invention provides a catalyst used for manufacturing an optically active carbonyl compound by selective asymmetric hydrogenation of an α, β-unsaturated carbonyl compound, which is insoluble in a reaction mixture, and a method for manufacturing the corresponding optically active carbonyl compound. Particularly, the invention provides a catalyst for obtaining an optically active citronellal useful as a flavor or fragrance, by selective asymmetric hydrogenation of citral, geranial or neral. The invention relates to a catalyst for asymmetric hydrogenation of an α, β-unsaturated carbonyl compound, which comprises: a powder of at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table, or a metal-supported substance in which the at least one metal is supported on a support; an optically active cyclic nitrogen-containing compound; and an acid, and also relates to a method for manufacturing an optically active carbonyl compound using the same.
