Methyl dihydrojasmonate (often referred to by its trade names of hedione or kharismal) is an aroma compound with an odour similar to that of jasmine.

[1] It was first synthesised in 1962[2][3] and is used in fine fragrances as well as cosmetics, toiletries, shampoos, soaps, and detergents.

Some of the earliest synthesis was based on the selective hydrogenation of methyl jasmonate, which was obtained from natural jasmin oil.

Modern synthesis involves the condensation of cyclopentanone and pentanal, followed by C=C bond isomerisation to give the 2-pentyl-cyclopentenone derivative.

[4] The name Hedione is derived from from Ancient Greek hēdonḗ, meaning "pleasure", c.f.
