, (2008/06/13)

The compounds according to the general formula in which formula the dotted lines indicate a single or a double bond, n and m are 0 or 1, R1is hydrogen or an acyl group —C(O)R3, R3being a linear or branched alkyl or alkylene group from C1to C8, the oxygen atom being bound to the adjacent α-carbon atom by a double bond in the case where n is 0 and by a single bond in the case where n is 1, R2is hydrogen or a linear or branched alkyl, alkenyl or alkoxy group from C1to C8, or R2is an alkenoxy group which is linked to the group R1to form a 1,3-dioxolane cycle having 5 to 7 ring members, are useful perfuming ingredients. The most preferred compounds according to the invention are those which have a damascone- or damascenone-like structure, with the methyl substituent being in 4-position of the ring instead of the 2-position, as is the case in damascones and damascenones.
