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 ##STR1## wherein R.sup.1 and R.sup.2 represent simultaneously or a independently a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms, R.sup.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.sup.4 represents a hydrogen or a linear alkyl group containing 1 to 4 carbon atoms. Substituents groups of R.sup.3 can be for example C.sub.1 -C.sub.3 alkyl or alkenyl groups, an aromatic ring or C.sub.5 -C.sub.7 cycloalkyl or cycloalkenyl groups, possibly substituted by methyl or ethyl groups.
