ABSTRACT:
Methyl dihydrojasmonate containing a major proportion of cis methyl dihydrojasmonate. The NMR spectrum of cis methyl dihydrojasmonate is illustrated in the attached drawings.
Cis methyl dihydrojasmonate displays olfactory properties superior to those of the trans isomer making it very useful as an odoriferous agent. In order to prepare methyl dihydrojasmonate containing a major proportion and preferably at least 90% of cis isomer, methyl (2-pentyl-3-keto-cyclopenten-1-yl)-acetate is catalytically hydrogenated in the presence of an aluminium derivative.
