.alpha.-Campholenic alcohol, dihydro-.alpha.-campholenic alcohol and the lower acyl esters thereof have organoleptic properties which make them useful as tobacco flavorants.

.alpha.-campholenic alcohol, dihydro-.alpha.-campholenic alcohol and

Compounds of the general formula ##STR1## wherein R is hydrogen or an acyl group of two to five carbon atoms and the dotted line is an optional bond, are valuable flavor compounds and can be used to improve the flavor of foodstuffs and luxury consumables.

Flavoring with .alpha.-campholenic alcohol

(2R*,3S*)-(E)-3-Methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl)pent-4-en-2-ol possesses a very intense creamy, woody, musk, sandalwood odor and is a valuable ingredient for use in fragrance compositions for its musk and sandalwood-like qualities. This odorant is more intense than any of the campholenic aldehyde derivatives that have been previously reported.

Terminal epoxides, also known as alpha-epoxides or 1,2-epoxides, are rearranged predominantly to the corresponding aldehydes using a catalyst system consisting of lithium tetrafluoroborate in a polyether solvent.

Process for the rearrangement of epoxides

There is disclosed a novel process for converting allylic amines, having a hydrogen bonded to a carbon .delta. to the amino group, to a diene in the presence of a zero valent palladium phosphine complex and a weak acid. The process has been used to make novel compositions containing 7-methoxy-3,7-dimethyloctadienes which are useful as odorants and flavorants.

Process for the catalytic synthesis of conjugated dienes from

3-Methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl)pentan-2-ol possesses a strong, precious woody odor reminiscent of sandalwood oil and is especially valuable in fragrance compositions.
