The Synthesis of Occidol

Abstract

The structure (I) of occidol, a new sesquiterpene alcohol isolated from the essential oil of the wood of Thuja occidentalis L. has been proposed in a recent paper. The structure is confirmed by (a) comparison of the infrared spectrum of the synthesized racemate with that of occidol, and (b), by the mixed m. p. of picrate of the synthesized 6-isopropyl-1, 4-dimethylnaphthalene with that of a dehydrogenated product of occidol.
