Compound of formula ##STR1## wherein a) indexes m and n are identical and stand each for an integer number equal to zero, symbols R.sup.1 and R.sup.2 are identical and represent each a hydrogen atom, or are different and represent each a hydrogen atom or a methyl radical, symbols R.sup.5 and R.sup.8 stand each for a methyl radical, symbols R.sup.6 and R.sup.7 can be identical or different and designate each a hydrogen atom or a methyl radical and, either symbol R.sup.4 represents a methyl radical and symbol R.sup.3 stands for a hydrogen atom or a methyl radical, or symbols R.sup.3 and R.sup.4 represent each a methylene radical belonging to a ring such as indicated by the dotted line, with the proviso that the following combinations are excluded: 1. R.sup.1 =R.sup.2 =R.sup.3 =R.sup.6 =R.sup.7 =H, or 2. R.sup.1 =R.sup.2 =R.sup.3 =H and R.sup.6 or R.sup.7 =CH.sub.3, or 3. R.sup.2 =CH.sub.3 and R.sup.3 =R.sup.6 =R.sup.7 =H, or 4. R.sup.2 =CH.sub.3 and R.sup.3 =H and R.sup.6 or R.sup.7 =CH.sub.3, or 5. R.sup.1 =R.sup.3 =CH.sub.3, or 6. R.sup.3 =R.sup.4 =CH.sub.2 and R.sup.2 or R.sup.7 =CH.sub.3 ; or wherein b) indexes m and n are different and define each an integer number equal to 0 or 1, symbol R.sup.2 stands for a hydrogen atom or a methyl radical, symbols R.sup.1 and R.sup.3 designate each a hydrogen atom, symbol R.sup.4 represents a methyl radical and, either symbols R.sup.5 and R.sup.6 are identical (n=1) and represent each a methylene radical belonging to a ring such as indicated by the dotted line, R.sup.7 representing a hydrogen atom and R.sup.8 a methyl radical, or symbol R.sup.5 stands for a methyl radical and symbol R.sup.6 for a hydrogen atom, R.sup.7 and R.sup.8 being then identical (m=1) and designating each a methylene radical belonging to a ring such as indicated by the dotted line; or any mixture of two or more structural isomers of formula (I). Compounds (I) develop odor notes of the musky type and can therefore be used as active ingredients in perfuming compositions and perfumed articles of varied nature. A process for the preparation of compounds (I) is described.
