摘要

Described for use in augmenting or enhancing the aroma or taste of smoking tobacco compositions or smoking tobacco articles are cyclohexenyl-alpha-alkyl acrolein derivatives defined according to the generic structure: <IMAGE> wherein R1, R2, R3 and R4 represent hydrogen or methyl with the proviso that one, two or three of R1, R2, R3 and R4 represent methyl; wherein R5 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, R5, cyclohexenyl and carboxaldehyde about the carbon-carbon double bond; or represented by the structures: <IMAGE>
