ABSTRACT:
The invention concerns pentene derivatives of the general formula (I), in which, independently of each other, R.sup.1 is hydrogen or a methyl group, R.sup.2 and R.sup.3 are hydrogen or an alkyl group with 1 to 5 C-atoms, R.sup.4 is hydrogen or a CHR.sup.5 R.sup.6 group (R.sup.5 and R.sup.6 being hydrogen or an alkyl group with 1 to 6 C-atoms) and X is a CO or CHOH group, with the provision that (a) at least one of the groups R.sup.2 and R.sup.3 is an alkyl group and (b) 2-methyl-4-(2,2,3-trimethyl-3-cyclopenten-1-yl)-4-penten-1-ol is excluded. Such compounds are odoriferous substances with interesting fragrances and high diffusion power.
