The present invention relates to certain ester and nitrile derivatives of formula (I):
wherein one dotted line represents a carbon-carbon single or double bond and the other dotted lines each represent a carbon-carbon single bond;
R
1
is a hydrogen atom or a methyl group, R
2
is a methyl or ethyl group, R
3
is a hydrogen atom or a methyl group, R
4
is a hydrogen atom or a methyl group or said R
4
taken together with the bond between carbon atom 2 and 3 form a cyclopropane; and
X represents a CN or a COOR
5
group, R
5
representing a C
1-5
alkyl group; with the compound being in the form of any one of its pure stereoisomers or mixtures thereof. These compounds are useful perfuming ingredients.
