RESUMO
An overview of the recent research which allowed us to discover novel animalic odorants is presented. The new derivatives were prepared from readily available starting materials via easy reaction steps in good yields. They possess very different structures, such as bicyclic pentanols, glycolates, or tricyclic ketones, and all show interesting notes in the animalic fragrant family: from costus, leathery to ambery and musky scents, making them all attractive for different purposes.

An overview of the recent research subjects in the perfumery field and, more precisely the synthesis of novel compounds for the hesperidic family of odorants, is presented. The new derivatives possess very different structures; nevertheless, they all share an aldehydic odor, but with diverse nuances, which make them all attractive for different purposes.

The optimization of a Diels-Alder reaction to prepare a novel ketone bearing a 2,3-dimethylnorbornyl group is presented together with the structure elucidation of the isomers. Employing this new ketone as starting material, derivatives with new woody odor notes as well as attempts to obtain ambery-musky odorants are reported.
