2-alkyl-4-phenyl-dihydropyrans and processes for augmenting the

Abstract

Described is the novel compound group, 2-alkyl-4-phenyl-dihydropyrans having the generic structure: ##STR1## where one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond, R.sup.1 is one of C.sub.1 -C.sub.3 alkyl, and R is one of C.sub.2 -C.sub.4 alkyl, a process for producing same; a process comprising adding to tobacco an amount sufficient to augment the flavor or aroma of such tobacco of one or more of said pyran compounds; flavor formulations for use in conjunction with tobacco products containing one or more of such pyrans; a process comprising adding to foodstuffs, foodstuff flavorings, chewing gums, chewing gum flavorings, toothpaste and toothpaste flavorings one or more of said pyran compounds in a quantity sufficient to augment or enhance neroli-like and grape-like flavors, and flavoring compositions containing said pyran compounds.
