Benzofuranone compounds, and production of smoking compositions containing a benzofuranone flavorant additive

摘要

This invention provides a process for the production of novel smoking compositions which contain a benzofuranone flavorant additive, and further provides novel benzofuranone compounds as illustrated by the cis 6-phenyl-3a, 4,5,7a-tetrahydro-2(3H)-benzofuranone: <IMAGE> Under normal cigarette smoking conditions, the benzofuranone additive in an invention smoking composition enhances the flavor and aroma of the mainstream and sidestream smoke.
