Cis Jasmone

Jasmone is a natural organic compound extracted from the volatile portion of the oil fromjasmine flowers. It is a colorless to pale yellow liquid that has the odor of jasmine. Jasmone can exist in two isomeric forms with differing geometry around the pentenyl double bond, cis-jasmone and trans-jasmone. The natural extract contains only the cis form, while synthetic material is often a mixture containing both forms, with the cis form predominating. Both forms have similar odors and chemical properties.

Jasmone is produced within plants by the metabolism of jasmonate, from linolenic acid by the octadecanoid pathway. It can act as either an attractant or a repellent for various insects. Commercially jasmone is used primarily in perfumes and cosmetics.

In fact one synthesis uses the following as carbon sources:
