Aleuritic Acid in Perfumery and Pheromones

The brief account given above indicates the vast potential which aleuritic acid holds in the synthesis of numerous useful organic compounds possessing olfactory properties. With a steady and substantial availability of threo aleuritic acid, its utility is expected to increase enormously.

Fragrant Esters of 3-Cyclohexylbutanoic Acid

Thus, the acid is not too easily available, but remarkable fragrant properties of its esters raise the interest in its production. The first four stages of its synthesis have been described previously. Prin’s reaction of α-methylstyrene with formaldehyde yields 4-methyl-4-phenyl-1,3-dioxane.

HESP—A New Essential Oil From the Acid Hydrolysate of Spent Sandal Heartwood

In the present study, the utilization of the spent (exhausted) sandalwood powder from steam distillation as a source of an acid hydrolysate oil is examined. It has been found that hydrolysis of the non-volatile portion of an acetone extract of the spent sandalwood powder with methanolic hydrochloric acid followed by steam distillation gave rise to a new essential oil (1.2% yield) which we have called HESP, the acronym for hydrolyzed exhausted sandalwood powder.

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.
