The present invention relates to the use in perfumery of compounds of the general formulae in which R1 and R2 are identical or different and represent each a methyl or ethyl group, R3 represents hydrogen or an alkyl group from C1 to C4, linear or branched, and R4 represents hydrogen, an alkyl group from C1 to C4, linear or branched, or an acyl group of formula R5C(O)-, R5 being hydrogen or an alkyl group from C1 to C4, linear or branched. The novel odoriferous character of these compounds is the combination of woody with fruity notes. Also described is a synthesis for the preparation of the compounds of formula (I) starting from the compounds of formula (II).
