tertiary carbon of simple ketones (1, 2 and 6), furanoeremophilane-type ketones (12–19), and tricyclic ketones (20–22) by the use of benzeneseleninicanhydride is described. 10β-Hydroxy compounds were obtained in the case of 12–14 and 20–22. 10α-Hydroxy compounds were obtained in the case of 15 and 16. In the hydroxylation reaction of polycyclic ketonesusingbenzeneseleninicanhydride, the results suggest

The present invention relates to use of a compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein the dotted lines represent a single or double bond, and at least one of said dotted lines represents a double bond; n represents simultaneously 0, in which case the oxygen atom is bounded to the cyclanic carbon atom by a double bond, or 1, in which case the oxygen atom is bounded to the cyclanic carbon atom by a single bond, each R represents a hydrogen atom or a methyl group; R1 represents a hydrogen atom or a methyl or ethyl group; and R2 represents a hydrogen atom or a methyl or ethyl group; and the groups R, R1 and R2 have in total, i.e. all together account for 1 to 4 carbon atoms; as perfuming ingredient, for instance to impart odor notes of the woody type together with balsamic/spicy and/or musky notes.
