ABSTRACT:
Described are compounds having the generic structure: ##STR1## wherein each of the lines ++++ and the wavy line represent single or carbon-carbon double bonds; wherein each of R.sub.2, R.sub.3 and R.sub.4 represents hydrogen or methyl and R.sub.1 ' represents hydrogen, methyl or methylene; wherein R.sub.5 represents C.sub.1 -C.sub.4 alkyl; with the proviso that when R.sub.2 is CH.sub.3, R.sub.1 ' is hydrogen and ++++ represents a single bond and the wavy line represents a carbon-carbon single bond or a carbon-carbon double bond; and with the further proviso that when R.sub.2 is hydrogen, R.sub.1 ' is methyl and ++++ represents a carbon-carbon single bond and the wavy line represents a carbon-carbon double bond or a carbon-carbon single bond or R.sub.1 ' is methylene (CH.sub.2) and ++++ is a carbon-carbon double bond and the wavy line is a carbon-carbon single bond 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, perfumed articles (such as liquid or solid anionic, cationic, nonionic or zwitterionic detergents, fabric softeners, dryer added fabric softener articles and cosmetic compositions), perfumed compositions, smoking tobaccos and smoking tobacco articles. Also disclosed is a process for preparing such compounds using the reaction scheme or parts of said reaction scheme: ##STR2## wherein R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are as defined above.
