Abstract: PROBLEM TO BE SOLVED: To provide a method of asymmetrically synthesizing optical activity menthol from one or more inexpensive achiral starting materials that do not require isolation from a natural supply source.SOLUTION: (a) Optical activity citronellol is obtained by enantio-selectively hydrogenating geraniol, nerol, or a mixture of geraniol and nerol, (b) optical activity citronellal is obtained by reaction of the obtained optical activity citronellol, (c) a mixture containing optical activity isopulegol is obtained by cyclizing the obtained optical activity citronellal, and (d) optical activity menthol is obtained by extracting the optical activity isopulegol from the obtained mixture and then hydrogenating it, or by hydrogenating the optical activity isopulegol contained in the mixture to produce optical activity menthol and then extracting the obtained optical activity menthol from the mixture obtained as a hydrogenated product. Thus, in this method, optical activity menthol is manufactured from geraniol, nerol, or a mixture of geraniol and nerol.
