Document Type and Number:
Japanese Patent JP4418554
Kind Code:
B2
Abstract:
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, R<1> is hydrogen or an acyl group -C(O)R<3>, R<3> being a linear or branched alkyl or alkylene group from C1 to C8, the oxygen atom being bound to the adjacent alpha -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, R<2> is hydrogen or a linear or branched alkyl, alkenyl or alkoxy group from C1 to C8, or R<2> is an alkenoxy group which is linked to the group R<1> to 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.
