Carvone

An aroma chemical profile: carvone. The basic organic chemical structure of the carvones is similar to that of the menthols and menthones. Thus, it is not surprising to discover a distinct organoleptic impression for each optical antipode. However, the organoleptic impressions are not similar to menthol or menthone, nor do the carvones display the cooling effect of menthol.

Synthetic Routes to Carvone

Methods leading to (–)-, (+)-, and (±)-carvone have been reviewed, The technical production of (–)-carvone is based on the widely available (+)-limonene; the most favored route is that epitomized in Chart 1. Though the steps involved are simple, their exploitation is a wellguarded secret, There is no similar commercialscale production of (+)-carvone because the basic materials for its synthesis are not as readily available. However, sooner or later the rising demand for this ketone will ensure that it, too, will be produced synthetically.
