New type odor molecule with Sandalwood, process for their preparation and use thereof as odorant.

摘要

The present invention comprises the preparation of a novel odorant (1), preparation thereof from (1R) - (-) - nopol (2) and use thereof as a sandalwood type ingredient in the production of perfumery compositions. Obtaining (1) from (2) is achieved in five steps with a global return of 25%, by means of the following transformations: (a) catalytic hydrogenation, (b) oxidation to hydroxile group aldehyde (c) aldol condensation of the resulting aldehyde with butanone, (d) deconjugation and a-methylation of the aldol condensation product, and (e) reduction of the carbonyl group
