Abstract: Disclosed is a method for producing an alcohol from a lactone or a carboxylic acid ester, which enables to produce an alcohol from a lactone or a carboxylic acid ester under relatively mild conditions with high yield and high catalytic efficiency. This method also enables to produce an optically active alcohol from an optically active lactone or an optically active carboxylic acid ester. Specifically disclosed is a method for producing an alcohol by hydrogen reducing a lactone or a carboxylic acid ester in the presence of a catalyst containing ruthenium and a phosphine compound represented by the following general formula (1): wherein R1 represents a spacer; R2, R3, R4, R5, R6 and R7 independently represent a hydrogen atom, an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group; and R8, R9, R10, R11, R12 and R13 independently represent an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group.

Abstract: Phosphine compounds represented by the following formula (1): wherein R1, R2, R3, R4, R5, R6 and R7 represent substituents, and asymmetric synthesis catalysts containing transition metal phosphine complexes with the compounds contained as ligands therein. The novel phosphine compounds according to the present invention are useful especially as ligands in transition metal complexes. The transition metal phosphine complexes are useful as catalysts for asymmetric synthetic reactions. The novel phosphine compounds useful as ligands can be prepared by a relatively economical preparation process. Further, use of these catalysts can afford hydrogenated products with high optically purity and is also extremely useful from the industrial standpoint.

Abstract: The present invention provides a method for producing optically active amines of formula (9) or (10): which comprises reacting an imine equivalent of formula (6): with an alkene of formula (7) or an alkyne of formula (8): in the presence of a chiral catalyst, which method does not require additional procedures such as introduction and removal of protecting groups and gives said amines with high purity and high operability. The optically active amines are useful as synthetic 15 intermediates for pharmaceuticals, agrochemicals, etc.
