Carboalkoxy alkyl norbornanes and process for preparing same

Abstract

Described are compounds having the generic structure: ##STR1## wherein the dashed line is either a carbon-carbon single bond or a carbon-carbon double bond and each of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represents hydrogen or methyl with the proviso that one of R.sub.2 and R.sub.1 is methyl and the other of R.sub.1 or R.sub.2 is hydrogen and R.sub.3 and R.sub.4 are not both methyl; and wherein R.sub.5 represents C.sub.1 -C.sub.4 alkyl are disclosed. In addition organoleptic uses of such compounds are disclosed for augmenting or enhancing the aroma or taste of consumable materials including foodstuffs, chewing gums, chewing tobaccos, medicinal products, toothpastes, perfumes, perfumed articles (such as liquid or solid anionic, cationic, nonionic or zwitterionic detergents) fabric softeners, dryer added fabric softener articles, and smoking tobaccos. 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 equals 3 with the proviso that m is one or two and n is one or two; and wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are defined as above.
