- CATALYST COMPOUNDS
-
The present invention relates to compounds, particularly but not exclusively, compounds for use as catalysts, methods for producing said compounds and the use of said compounds as catalysts in catalytic processes including, but not limited to, the asymmetric reduction of imine and enamine compounds and/or the reductive amination of ketone compounds. The compounds have the formula 1 wherein: R1, R2, R3, R4 and R5 are each separately selected from the group consisting of hydrogen, alkyl and aryl; X is oxygen or sulfur; W is selected from the group consisting of – OR18,–SR18, –NR19R20, –PR19R20 where R18 is alkyl or aryl, and R19 and R20 are each separately selected from the group consisting of hydrogen, alkyl and aryl; and Z has the formula 2 wherein: R6 and R7 are each separately selected from the group consisting of hydrogen, alkoxy, nitro, halogen, alkyl and aryl, or R6 and R7 are linked to form a cyclic group; and Y is oxygen, sulfur or NR10 in which R10 is selected from the group consisting of hydrogen, alkyl and aryl.

- CATALYST COMPOSITIONS AND THEIR USE IN THE DE-ENRICHMENT OF ENANTIOMERICALLY ENRICHED SUBSTRATES
-
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.

- Highly regioselective hydrogenolysis of bis(α-methylbenzyl)amine derivatives affected by the trifluoromethyl substituent on the aromatic ring
-
(Matrix presented) The highly regioselective hydrogenolysis of bis(α-methylbenzyl)amine derivatives proceeded with influence not from the electronic effect but from the steric effect of the trifluoromethyl substituent on the aromatic ring to provide a practical asymmetric synthesis of trifluoromethyl-substituted α-phenylethylamines.
