(E)&(Z)-4,8-Dimethyl-3,7-nonadien-2-one Chemical Properties, Uses, Production

Chemical Properties

(E) and (Z)-4,8-Dimethyl-3,7-nonadien-2-one has a floral-fruity odor. In a U.S. patent, the olfactory properties of this compound have been described as fruity, fresh, acetate, rose oxide, aqueous grapefruit, melon, fresh, bergamot and rosemary

Synthesis

Prepared by the reaction of 8-dimethyl-3,7-nonadien-2-ol in the presence of a catalyst and hydrogen acceptor (alphaamylcinnamaldehyde and aluminum isopropoxide). 8-Dimethyl-3,7-nonadien-2-ol may be synthesized by a Grignard reaction from citral and methylmagnesium chloride.
