✦ Synopsis

The occurrence of three aromatic sesquiterpene hydrocarbons in Reunion vetiver oil is reported for the first time. One of these was identified as a-calacorene. The others were found to be new compounds. Spectral and gas chromatographic characteristics as well as the results of hydrogenation and dehydrogenation experiments on the new sesquiterpenes, called A and B, are recorded. Sesquiterpene A may be tentatively represented as a dehydrocurcumene (VI), while sesquiterpene B is a cadalene-type hydrocarbon.

Hydroboration was carried out on terpinolene, myrcene, a-and B-cedrene, a-and P-caryophyllene and caryophyllene oxide. Some of the corresponding terpenic alcohols were isolated and characterized. These are potentially of interest as fragrances in perfumery.
