Abstract

Abstract Described are cyclohexenyl-alpha-alkyl acrolein derivatives defined according to the generic structure: ##STR1## wherein R 1 , R 2 , R 3 and R 4 represent hydrogen or methyl with the proviso that one, two or three of R 1 , R 2 , R 3 and R 4 represent methyl; wherein R 5 represents methyl or ethyl; wherein one of the dashed lines represents a carbon-carbon double bond and the other of the dashed lines represents a carbon-carbon single bond; wherein the wavy lines represent the "cis" or "trans" juxtaposition of the moieties hydrogen, R 5 , cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; or represented by the structures: ##STR2## and 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, perfumed articles, colognes, smoking tobaccos and smoking tobacco articles using as the essential ingredient at least one of said cyclohexenyl-alpha-alkyl acrolein derivatives.
