The new decane / decene tricyclic derivatives AB5.2.1.02,6 BD of formula A in which Rd, in the case where Rd = -CH3, is in position C7 or C8, the dotted lines between C3 and C4 and C4 and C5 represent either two CC single bonds or one double bond and one CC single bond and the wavy lines represent stereoisomeric forms, can be prepared by deconjugation of the corresponding unsaturated alpha, beta carbonyl compounds followed, where appropriate, by reduction and are preferably used as perfuming substances, in particular in perfume compositions for perfuming cosmetic and technical products. |
