Page/Page column 17-18, (2009/04/23)
There is provided a method for producing an optically active 1-(fluoro-, trifluoromethyl- or trifluoromethoxy-substituted phenyl)alkylamine N-monoalkyl derivative, which includes the steps of conducting reductive alkylation of an optically active secondary amine and a formaldehyde (including an equivalent thereof) or lower aldehyde in the presence of a transition metal catalyst under a hydrogen gas atmosphere, thereby converting the secondary amine to an optically active tertiary amine of the formula, and subjecting the tertiary amine to hydrogenolysis. The target optically active compound can be produced efficiently by this production method.

Page/Page column 22-23, (2008/06/13)
There is provided a process for the de-enrichment of enantiomerically enriched compositions which comprises reacting an enantiomerically enriched composition comprising at least a first enantiomer or diastereomer of a substrate comprising a carbon-heteroatom bond, wherein the carbon is a chiral centre and the heteroatom is a group V heteroatom, in the presence of a catalyst system and optionally a reaction promoter to give a product composition comprising first and second enantiomers or diastereomers of the substrate having a carbon-heteroatom bond, the ratio of second to first enantiomer or disatereomer in the product composition being greater than the ratio of second to first enantiomer or disatereomer in the enantiomerically enriched composition. Preferred catalyst systems include transition metal halide complex of the formula MnXpYr wherein M is a transition metal; X is a halide; Y is a neutral optionally substituted hydrocarbyl complexing group, a neutral optionally substituted perhalogenated hydrocarbyl complexing group, or an optionally substituted cyclopentadienyl complexing group; and n, p and r are integers. The reaction promoter is preferably a halide salt.
