Provided is a catalyst for producing an optically active aldehyde by selective asymmetric hydrogenation of an α, β-unsaturated aldehyde, particularly a catalyst that is insoluble in the reaction mixture and is used to obtain optically active citronellal, which is useful as a fragrance, by selective asymmetric hydrogenation of citral, geranial or neral. Also provided is a method for producing the corresponding optically active aldehyde. The α, β-unsaturated aldehyde is subjected to asymmetric hydrogenation using a solid catalyst comprising an optically active compound and a metal-supporting product wherein a carrier supports at least one metal selected from the group consisting of the elements in Groups 8 through 10 of the Periodic Table.
本发明提供了一种通过选择性不对称氢化α,β-不饱和醛来生产光学活性醛的催化剂,特别是一种不溶于反应混合物的催化剂,可用于通过选择性不对称氢化柠檬醛、香叶醇或橙花醛来获得光学活性香茅醛,这种香茅醛可用作香料。此外,还提供了一种生产相应光学活性醛的方法。α,β-不饱和醛使用固体催化剂进行不对称氢化,固体催化剂由光学活性化合物和金属支持产物组成,其中载体支持至少一种选自元素周期表第 8 至 10 族元素组成的组的金属。
