The compounds of formula ##STR1## wherein symbol X designates a C.dbd.O (Ia) or C(CH.sub.3)--OC(O)CH.sub.3 (Ib) group and the dotted line indicates the location of a single or double bond in formula (Ia) and of a double bond in formula (Ib), are characterised by useful odor notes of the aromatic, fruity, even amber type and can as a result be advantageously used as active perfuming ingredients.
