Abstract

A process far preparing cis-dihydronopol and esters thereof in which corresponding esters of (-)nopol are stereoselectively hydrogenated by heterogeneous hydrogenation in the presence of a platinum, platinum oxide or ruthenium/carbon catalyst, and the resulting cis-dihydronopyl esters optionally may be converted into correspanding alcohols by hydrolysis.
