Compounds of the formula ##STR1## in which one of the radicals R.sup.1 and R.sup.2 is methyl and the other is vinyl and one of the radicals R.sup.3 and R.sup.4 is methyl and the other is ##STR2## in which R.sup.5 is hydrogen, alkyl or alkenyl, in particular C.sub.1 -C.sub.6 -alkyl or C.sub.2 -C.sub.6 -alkenyl, are particularly suitable as fragrances and flavors.

8-Ocimenyl esters and fragrances and flavors containing the same

Compounds of the formulae ##STR1## in which R is hydrogen or methyl, and the dashed lines represent an additional bond in the 11- or 12-position, have extraordinary olfactory properties.

Macrocyclic lactones as musk fragrance enhancers

Certain 2-carbonylbenzofurans and 2-carbonyl-2,3-dihydrobenzofurans are excellent odoriferous substances.

Use of substituted 2-acetylbenzofurans as odoriferous substances

Ethylvanillin isobutyrate is a valuable new fragrance and flavor substance which, because of its extraordinary organoleptic profile and its favorable technical properties, permits hitherto unknown effects in perfumery and flavoring.

Ethylvanillin isobutyrate

Use of 3-acylthiohexyl esters of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.5 -C.sub.12 -aryl, including furyl and thienyl, as aroma and/or odoriferous substances, and aroma and odoriferous substance compositions containing these compounds.

Use of 3-acylthiohexyl esters as aroma and odoriferous substances
