PROCESS FOR PREPARING ENANTIOMERIC PUREES 6,8-DIHYDROXYOCTANIC ACID ESTERS BY ASYMMETRIC CATALYTIC HYDROGENATION

摘要

The invention relates to a process for the preparation of compounds of the general formula I in which RSUP1 /SUPrepresents a CSUB1/SUB-CSUB20/SUB-alkyl group, a CSUB3/SUB-CSUB12/SUB-cycloalkyl group, a CSUB7/SUB-CSUB12/SUB-aralkyl group or a mono- or bi-nuclear aryl group, in which a ketone of formula II wherein RSUP1 /SUPis as defined above, is subjected to asymmetric hydrogenation.
