New alicyclic ketoesters having the generic formula ##SPC1## Wherein R represents a hydrocarbon radical containing from 4 to 8 carbon atoms, and R' represents an alkyl radical containing from 1 to 2 carbon atoms, are prepared, in one embodiment, by condensing the methyl or ethyl ester of propane-1,2,3-tricarboxylic acid with methyl or ethyl esters of 2-bromo acids containing from 6 to 10 carbon atoms, and hydrolyzing, decarboxylating and re-esterifying the resulting cyclic keto-triesters. The new compounds have olfactory properties and are useful in the production of a great variety of perfumes.
