Abstract
The invention concerns a method for preparing an optically active alcohol of formula (I) in which the carbon atom indicated by the symbol * can have the configuration (R) or (S) and X represents a non-substituted amino group or a mono- or di-(C.sub.1 -C.sub.4)alkylamino group optionally salified from corresponding ketones by catalytic hydrogenation in the presence of a rhodium complex.
