摘要:
2-Alkylidene-3,3,5(3,5,5)-trimethylcyclopentanones corresponding to the following general formula ##STR1## in which three of the substituents R.sub.1 to R.sub.4 are CH.sub.3, one of the substituents R.sub.1 to R.sub.4 is H, and R.sub.5 is a saturated or unsaturated, linear branched C.sub.1 -C.sub.7 alkyl radical, and the double bond is in the endo position to the cyclopentanone structure. The compounds of formula (I) are useful as perfumes.
