The present invention relates to the perfumery and flavor industry. It concerns more particularly the use of a compound of formula (I) as perfuming or flavoring ingredient <CHEM> wherein R<1> and R<2> represent simultaneously or a independently a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms, R<3> represents a hydrogen, a cycloalkyl or a cycloalkenyl group, possibly substituted, a furanyl group, possibly substituted, a linear or branched alkyl or alkenyl group containing 1 to 12 carbon atoms, possibly substituted, or a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms terminated by a carboxyl ester or amide group; and R<4> represents a hydrogen or a linear alkyl group containing 1 to 4 carbon atoms. <??>Substituents groups of R<3> can be for example C1-C3 alkyl or alkenyl groups, an aromatic ring or C5-C7 cycloalkyl or cycloalkenyl groups, possibly substituted by methyl or ethyl groups. |
