Dihydrojasmone was easily synthesized by bromination of 4-methyl-3-pentyl-4-penten-2-one, which was obtained by the alkylation of mesityl oxide, followed by the treatment with a base.

2,3,5-trisubstituted-2-cyclopentenones or 2,3-disubstituted-2-cyclopentenones (such as cis-jasmone) are prepared by contacting a 3-chloro-3,4-disubstituted-4-pentene-2-one with a strong base. Methods of preparing the reactants are also disclosed.
