  Hydride reduction of alpha, beta-unsaturated carbonyl compounds using chiral organic catalysts

  摘要：

  非金属手性有机催化剂被用于催化α，β-不饱和羰基化合物的1,4-氢化物还原。α，β-不饱和羰基化合物可以是醛或环酮，氢化物供体可以是二氢吡啶。该反应是对映选择性的，并且可以使用多种氢化物供体、催化剂和底物进行。该发明还提供了用于进行α，β-不饱和羰基化合物的1,4-氢化物加成的有效组合物。

  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 peptide compound; and an acid, and also relates to a method for manufacturing an optically active carbonyl compound using the same.

  本发明提供了一种用于通过选择性不对称加氢α，β-不饱和羰基化合物制备光学活性羰基化合物的催化剂，该催化剂在反应混合物中不溶解，并提供了制备相应光学活性羰基化合物的方法。特别地，该发明提供了一种催化剂，通过选择性不对称加氢柠檬醛、香叶醛或柠檬醛制备出用作香料或芳香剂的光学活性香茅醛。该发明涉及一种用于不对称加氢α，β-不饱和羰基化合物的催化剂，包括：来自周期表第8至第10族金属中至少一种金属的粉末，或者至少一种金属负载物质，其中至少一种金属负载在一种载体上；一种光学活性肽化合物；和一种酸，还涉及使用该催化剂制备光学活性羰基化合物的方法。

  This invention aims at providing a catalyst for producing an optically active aldehyde or an optically active ketone, which is an optically active carbonyl compound, by carrying out selective asymmetric hydrogenation of an α,β-unsaturated carbonyl compound, particularly a catalyst which is insoluble in a reaction mixture for obtaining optically active citronellal which is useful as a flavor or fragrance, by carrying out selective asymmetric hydrogenation of citral, geranial or neral; and a method for producing a corresponding optically active carbonyl compound. 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 at least one metal selected from metals belonging to Group 8 to Group 10 of the Periodic Table is supported on a support, an optically active cyclic nitrogen-containing compound and an acid.
