Abstract
Cyclic isolongifolenyl ethers of the general formula A, where wavy lines mean α- and β-configuration, and R is the following radicals. 1 R=Me, Et, Pr, iso-Pr, Bu, sec-Bu, iso-Bu, tert-Bu. These isolongifolenyl ethers are excellent fragrances and can, in particular, be used as a constituent of fragrance mixtures or perfume oil for the perfuming of cosmetic or technical consumer goods. Also described are processes for the preparation of said cyclic isolongifolenyl ethers.
