PCT No. PCT/FR97/01154 Sec. 371 Date Mar. 24, 1999 Sec. 102(e) Date Mar. 24, 1999 PCT Filed Jun. 27, 1997 PCT Pub. No. WO98/00375 PCT Pub. Date Jan. 8, 1998The present invention relates to a process for the asymmetric hydrogenation of a ketonic compound and derivative. The invention relates to the use of optically active metal complexes as catalysts for the asymmetric hydrogenation of a ketonic compound and derivative. The process for the asymmetric hydrogenation of a ketonic compound and derivative is characterized in that the asymmetric hydrogenation of said compound is carried out in the presence of an effective amount of a metal complex comprising as ligand an optically active diphosphine corresponding to one of the following formulae:
