Isolongifolanone is a mixture isomer liquid with persistent woody and earthy odors. And smelled like patchouli and rock orchid.
According U.S. Patent No.3718698 that Isolongifolanone can be oxidized with sodium dichromate in acetic acid to provide a mixture of saturated and unsaturated ketones. It was further suggested in this Netherlands specification that the mixture of compounds so obtained could be used in perfume compositions. The mixture so formed contained relatively small amounts of the saturated ketone.
The other process is the preparation of a sesquiterpene ketone, e.g. cedranone, isolongifolanone and thujopsanone, wherein a C15H24 sesquiterpene hydrocarbon having an endocyclic double bond, e.g. cedrene, isolongifolene and thujopsene, is reacted with hydrogen peroxide in the presence of a C1-5 alkyl formate.
