Described are compounds having the generic structure: ##STR1## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and wherein R.sub.2 is methyl or hydrogen; R.sub.6 is methyl or hydrogen; R.sub.1, R.sub.3 or R.sub.7 represent methyl or hydrogen, with the proviso that one of R.sub.1, R.sub.3 and R.sub.7 represents methyl and the other two of R.sub.1, R.sub.3 and R.sub.7 represent hydrogen; wherein R.sub.4 and R.sub.5 are the same or different and each represents hydrogen or C.sub.1 -C.sub.3 lower alkyl. In addition, organoleptic uses of such compounds are disclosed for augmenting or enhancing the aroma or taste of consumable materials including foodstuffs, chewing gums, toothpastes, medicinal products, chewing tobaccos, smoking tobaccos, smoking tobacco articles, perfumes, perfumed articles (such as liquid or solid anionic, cationic, nonionic or zwitterionic detergents, fabric softeners, dryer-added fabric softener articles, fabric brighteners and other perfumed articles and colognes). Also disclosed is a process for preparing such compounds according to the reaction scheme: ##STR2## wherein R" represents C.sub.1 C.sub.3 alkyl; m+n=3 with the further proviso that m is 1 or 2 and n is 1 or 2; and wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 are as defined above.
A process for augmenting or enhancing the aroma or taste of a smoking tobacco flavor, a smoking tobacco composition or a smoking tobacco article comprising the step of adding to a smoking tobacco flavor, a smoking tobacco composition or a portion of a smoking tobacco article at least one norbornane derivative defined according to the structure:
A smoking tobacco article comprising a cylindrical shaped body of smoking tobacco contained within a wrapper and having on one end thereof a filter;
