Method for producing enantiomer-free 6,8 dihydroxy octanoic acid esters by means of asymmetric, catalytic hydrogenation

摘要

The invention relates to a process for the preparation of compounds of the general formula I in which R<1 >represents a C1-C20-alkyl group, a C3-C12-cycloalkyl group, a C7-C12-aralkyl group or a mono- or bi-nuclear aryl group, in which a ketone of formula II wherein R<1 >is as defined above, is subjected to asymmetric hydrogenation.
