Process for preparing optically active arylacetic acid derivative |
| abstract |
An optically active arylacetic acid derivative of the formula: ##STR1## wherein R 1 and R 2 are the same or different and are each an hydrogen atom, a lower alkyl group or a phenyl group; and Ar is a group of the formula: ##STR2## a group of the formula: ##STR3## wherein R 3 and R 4 are the same or different and are each a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a difluoromethoxy group, a trifluoromethyl group or a phenyl group is prepared in good conversion and optical yield by asymmetrically reducing an ethylenically unsaturated compound of the formula: ##STR4## wherein R 1 , and R 2 and Ar are the same as defined above with hydrogen in the presence of a metal catalyst modified with a ligand selected from the group consisting of a specific optically active metallocenyl phosphine derivative and a specific optically active binaphthyl derivative. |
