Transition from (+)-Car-3-ene to fragrant chemicals

For half a century, (+)-car-3-ene was relegated to the backyard of the Naval Stores Industry. More than anything else, lack of precise knowledge of its intricate chemistry and its non-availability in technical purity were responsible for this tragic negligence. Recent years have witnessed a dramatic change in the status of (+ )-car-3-ene. The terpene has blossomed into a unique raw material for modification to interesting and valuable perfumery synthetics.

A peep into p-menth-1-ene chemistry

When Semmler elucidated the structure of p-menth-1-ene by oxidative degradation in 1903, little was it thought that this simple hydrocarbon would serve as a substrate for the exciting researches which we have delineated. Today, scientists devoted to aroma chemistry are well aware of the sensory properties pertaining to odor and taste of the products mentioned in this paper. Available readily in optically active and inactive forms, p-menth-1-ene still challenges us with problems of far-flung consequences.

Acetals and Ketals of 3β, 4β-caranediol-New Odoriferous Compounds from (+)-3-carene

In summary, it is noteworthy that the odor characteristics of acetals and ketals of bicyclic terpenic diols have been absent in the literature. Our discovery of interesting odors of ketals of (+)-3β,4β-caranediol indicates further potential possibilities of synthesis of new odoriferous compounds in the series of bicyclic terpenic diols.

Vionil (10% in Dipropylene Glycol) (BRI 640DPG) Bedoukian Research www.bedoukian.com Vionil (640DPG) (CAS# 67019-89-0) is a long-lasting ingredient that is detectable on blotter for up to a week once dipped. Its odor presents an intense green floral character, particularly violet, accompanied by subtle notes of walnut. At trace levels, this powerful nitrile is excellent for adding green floral notes to fragrance applications where aldehydes are not stable.
