    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: The present invention relates to novel poly-alkylated benzodioxin compounds possessing a musk-like aroma which are useful as fragrance materials. The compounds of the invention have the formula: ##STR1## where R.sup.1 to R.sup.4 are hydrogen or lower alkyl (C.sub.1 to C.sub.5), provided that the compound has no more than 18 carbon atoms. The invention provides for synthesis of a novel phenolic intermediate and synthesis of the compounds of the invention. The invention also provides fragrance compositions which utilize the compounds of the invention to modify, enhance, or impart a musk-like aroma to perfume compositions, colognes and perfumed articles.
