New odoriferous compounds, in particular the compounds of formula (FORMULA) in which R is an aliphatic residue of formula (FORMULA) in which R1 is a C1-4 alkyl, a C1-4 alkylidene or a C2-4 alkenyl, the sum of the carbon atoms being established in these residues from 2 to 5, m and n being zero or to 1, p being 1, 2 or 3 and the dotted lines signifying one or two optional double bonds. The invention also also relates to a process for the preparation of new di-ketones I; as well as the use of I as odoriferous compounds in perfumed compositions, distinguished by a certain level of compounds of formula I. |
