Norbornylbutadiene-acrolein adducts, process for preparing same and perfumery uses thereof

摘要

Described is a genus of norbornylbutadiene-acrolein adducts defined according to the structure: ##STR1## wherein one of X.sub.1 or X. sub.2 represents carboxaldehyde and the other of X.sub.1 or X.sub.2 represents hydrogen; wherein R.sub.1 and R.sub.2 taken together represent vinyl or ethylidene and R.sub.3 represents hydrogen or R.sub.2 and R.sub. 3 taken together completes a cyclopenteno moiety and R.sub.1 represents hydrogen and uses thereof in augmenting or enhancing the aroma of consumable materials selected from the group consisting of perfume compositions, colognes and perfumed articles (e.g., perfumed polymers, solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, dryer-added fabric softener articles, hair preparations, hair sprays, bath preparations and the like). Also described is a process for preparing norbornylbutadiene-acrolein adducts comprising the step of reacting the compound defined according to the structure: ##STR2## with acrolein in the presence of a Lewis acid catalyst.
