Abstract: Cyclic ethers or chloroketones useful as fragrance components or intermediates are made by reacting a saturated, tertiary terpene alcohol with hypochloric acid under conditions effective to promote oxidation. trans-Pinanol gives predominantly 6,9-dimethyl-7-oxatricyclo[4.3.0.03,9]-nonane, while cis-pinanol yields almost exclusively 1-acetyl-3-(2-chloroethyl)-2,2-dimethylcyclobutane, a new and versatile intermediate for making cyclobutane derivatives having interesting and diverse aromas.

Abstract: A process for obtaining alpha-campholenic aldehyde, which is useful as an aroma chemical and as a synthetic intermediate for other aroma chemicals, particularly those with a sandalwood odor, and also for some pharmaceuticals, is provided. In particular, the invention includes a continuous process for obtaining optically active or racemic &agr;-campholenic aldehyde by a catalytic rearrangement of optically active or racemic &agr;-pinene oxide that can be commercially practicable. In one embodiment, the method comprises continuously feeding &agr;-pinene oxide to a mixture including catalyst(s) and solvent(s), where the solvent(s) have a boiling point higher than the boiling point of &agr;-campholenic aldehyde, under conditions sufficient to provide for the complete, or at least partial, conversion of &agr;-pinene oxide into &agr;-campholenic aldehyde. The process further includes continuously removing &agr;-campholenic aldehyde from the reaction zone by suitable techniques such as distillation.

Abstract: In a process for hydrogenation, with elemental hydrogen gas in the presence of a hydrogenation catalyst, of a cyclic unsaturated compound having an hydroxyl group projecting from an asymmetric center of the ring and an olefinic carbon-to-carbon double bond which when saturated in the hydrogenation process creates an additional asymmetric center in the ring, the improvement for obtaining increased stereoselectivity by increasing the addition of said hydrogen to that side of the olefin bond on the same side of the compound molecule as said hydroxyl group, comprising: conducting said hydrogenation with a nickel hydrogenation catalyst that has a substantial fraction of its reactive surfaces inactivated.The invention is particularly applicable to the hydrogenation of d-trans-piperitol to d-isomenthol.

Abstract: An improved process for the preparation of unsaturated terpene alcohols such as myrcenol and cis and trans ocimenol is described. Acyclic terpene allylic halides are reacted with a tertiary amine of the formula hereinafter described to form the corresponding quaternary ammonium salt which is then acidified to remove the ethylenic unsaturation between the 6th and 7th carbon atom and adding a hydroxy substituent on the 7th carbon atom of the terpene halide salt. The hydrated terpene ammonium halide salt is made neutral and thermally decomposed into the unsaturated terpene alcohols. Myrcenol and ocimenol cis and trans are useful for their fragrance and aroma in perfumery and cosmetic manufacture.
