A perfume composition contains methyl ℓ-3,7-dimethyl-7-hydroxyoctylideneanthranilate of the following formula (I):
in an amount of 0.1 to 50 wt%, together with other conventional perfume components. Two synthesis routes are given.
The compound has an orange-flower note. The composition is less allergenic and is safer than those containing the corresponding d- or dℓ-form, and it has a less irritating odor and imparts a clean and green note.

A PRACTICAL SYNTHESIS OF MYRCENOL BY PALLADIUM COMPLEX-CATALYZED ELIMINATION REACTION
A Palladium complex-catalyzed elimination reaction of allyl amines was studied to establish a practical process for production of myrcenol. The catalytic elimination occurred smoothly with the cationic Pd(II) complexes. Among a variety phosphorous ligands, the tetramethylene and the pentamethylene diphosphine ligands proved to be the best ligand with respects to the catalytic activity and selectivity.
