Način dobijanja
Methyl dihydrojasmonate is prepared by Michael addition of malonic acid esters to 2-pentyl-2-cyclopenten-1-one, followed by hydrolysis, decarboxylation and esterification. 2-Pentyl-2-cyclopenten-1-one is prepared by an aldol condensation between cyclopentanone and valeraldehyde and subsequent isomerization. High-cis material can be produced from the equilibrium mixture by special distillation techniques in which isomerization is effected by the action of sodium carbonate. An industrial process for a methyl dihydrojasmonate with a high portion of the (+)-(1R)-cis-isomer uses catalytic hydrogenation of the corresponding cyclopenteneacetic acid in the presence of a ruthenium(II) complex with chiral ligands, followed by esterification.

U parfemima
Methyl dihydrojasmonate is used in perfumery for blossom fragrances, particularly in jasmine types. It is a fragrance ingredient in perfumes, toilette and laundry products. As a flavor ingredient it produces fruit, tea, tobacco and floral flavors. High-cis methyl dihydrojasmonate is used in fine fragrances. It tends to isomerize into the equilibrium mixture, so it has only limited usage in other perfumery applications.
