This invention provides smoking compositions which contain a novel heteroaromatic flavorant-release additive as illustrated by the following structure:
where R is hydrogen or a C₁-C₄ alkyl group; R¹ is hydrogen or a C₁-C₈ alkyl group; and R² is a C₃-C₁₂ aromatic substituent; with the proviso that at least two R¹ groups are C₁-C₈ alkyl radicals.Under typical cigarette smoking conditions, 2-isopropylpyrazine and acetophenone are released as pyrolysis products, and enhance the flavor and aroma of the mainstream and sidestream smoke.
