New Aroma Chemicals: Thujone Alternatives

Perfumers often use the descriptor “thujone” to describe a particular note in fragrances. However, the odor of thujone itself seems to be inseparable from the character of the essential oils in which it is found. This article will examine the uses of thujone and thujone containing materials in perfumery, and describe some synthetic materials — old and new— that are intended to provide this note.

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.

Base-catalysed of terpenes

We have projected in the foregoing survey significant advances in the isomerisation of terpenes by base catalysis. Invoking this technique, it si seen how many of the delicate reactions are smoothly accomplished, adding new dimensions to terpene technology. How terpenes, which are notoriously sensitive to thermal and proton impact, have been engineered in the desired direction through base catalysis is an important chapter in the history of terpene chemistry.

Challenge Precedent Question Tradition

As an alternative, I thought it might he interesting to share my observations of some of yesterday’s fragrance industry precepts which have become today’s myths from my perspective as a professional consultant who for six years ran a conglomeration of companies ranging from motion picture distribution to fast-food franchising.
