Methyl substituted norbornane carboxaldehydes, organoleptic uses thereof and process for preparing same

摘要

Described are methyl-substituted norbornane carboxaldehyde having the generic structure: <IMAGE> wherein the dashed line is a carbon-carbon single bond, or a carbon-carbon double bond, and R1 R2 and R3 each represent methyl or hydrogen with the proviso that (i) R1 is hydrogen when R3 is methyl and (ii) R1 is methyl when R3 is hydrogen. Also described are processes and compositions for augmenting or enhancing the flavor and/or aroma of consumable materials including foodstuffs, chewing gums, medicinal products, toothpastes, chewing tobaccos, perfumes, colognes and perfumed articles such as solid or liquid anionic, cationic, nonionic or zwitterionic detergents or fabric softeners or fabric softener articles using as the essential ingredient at least one of the methyl substituted norbornane carboxaldehydes of our invention.
