The present invention relates to novel musk compounds, useful as fragrance materials which have the structure: ##STR1## wherein R is hydrogen or methyl and R.sub.1 and R.sub.2 are hydrogen, methyl, or ethyl, and provides methods for preparing these compounds from readily available intermediates. The invention also provides fragrance compositions which include the compounds, and processes for altering the organoleptic properties of perfume compositions, colognes and perfumed articles by adding organoleptically effective amounts of the compounds.

Process for the preparation of aromatic musks

Aromatic musks

Esters of 1,2,3,6-tetrahydrobenzyl alcohol have been found to exhibit powerful odorous notes such as floral, woody and fruity notes, rendering such compounds valuable as fragrance materials either alone or in compositions. These 1,2,3,6-tetrahydrobenzyl alcohol esters are prepared by reacting 1,2,3,6-tetrahydrobenzyl alcohol with an appropriate organic acid.

1,2,3,6-Tetrahydrobenzyl alcohol esters and compositions containing the

The perfume compositions of this invention contain hexyloxyacetonitrile which contributes unique olfactory properties reminiscent of irone with a flowery, herbaceous by-note. Hexyloxyacetonitrile can be incorporated readily in a wide variety of perfume compositions to enhance, diffuse and prolong the odor characteristics of such compositions.

The effect of the characteristic odor note of Oak Moss in the combination of components in perfume compositions can be achieved by substituting 2,4-dihydroxy-3-methyl-benzaldehyde, produced in a one step synthesis from readily available material, for Oak Moss which is available only in limited quantities at high cost.
