1,3-oxathianes as perfuming and flavouring ingredients

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 wherein R1 and R2 represent simultaneously or a independently a linear or branched alkyl or alkenyl group containing 1 to 4 carbon atoms, R3 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 R4 represents a hydrogen or a linear alkyl group containing 1 to 4 carbon atoms. Substituents groups of R3 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.
