    摘要: The present invention provides organoleptic compositions which upon thermolyis, hydrolysis or both, release an odorant molecule. They find utility, for example, in tobacco, in tobacco paper, and as additives to food, beverages or gum. The compositions contain one or more dicarboalkoxy dioxolane derivatives having the following formula: ##STR1## wherein R.sup.1 and R.sup.2 are, independently, --CO.sub.2 R.sup.3 wherein R.sup.3 is --H.sub.3 or lower alkyl, provided that in at least one of R.sup.1 and R.sup.2, R.sup.3 is lower alkyl; wherein Z is a direct bond, or --CH.dbd.C(R.sup.4)--; where R.sup.4 is --H or alkyl group; and Y is ##STR2## where R.sup.5 and R.sup.6 are independently --H, lower alkyl or --OR.sup.7 where R.sup.7 is --H or lower alkyl.

    摘要: Alicyclic ketone and alcohol derivatives having the structure: ##STR1## wherein the dotted line represents a carbon-carbon double bond or a carbon-carbon single bond; wherein Z is ##STR2## and wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 is hydrogen or lower alkyl are useful as odor-modifying ingredients in perfumes and perfumed products and as flavor-modifying ingredients in foodstuffs and tobacco products. These derivatives may be prepared from substituted phenols having the structure: ##STR3##
