Die vorliegende Erfindung betrifft primär die Verwendung von Dioxolanen der nachfolgenden Formel (I) als Riech- und/oder Aromastoff, bestimmte Riechstoff- und/oder Aromastoffkompositionen umfassend diese Dioxolane sowie entsprechende parfümierte und/oder aromatisierte Artikel.Ferner betrifft die vorliegende Erfindung ein Verfahren zur Herstellung der Dioxolane der Formel (I) sowie bestimmte neue Dioxolane gemäß der Formel (I).Perfume and/or flavoring composition comprises >= 1-3 substituted 4-vinyl-[1,3]dioxolane derivatives (I) and their stereoisomers, and at least >= 3-8 further perfumes and/or flavoring substances, which does not comprise (I), where the composition does not comprise 2-hexyl-4-vinyl-1,3-dioxolane. Perfume and/or flavoring composition comprises >= 1-3 substituted 4-vinyl-[1,3]dioxolane derivatives of formula (I) and their stereoisomers, and at least >= 3-8 further perfumes and/or flavoring substances, which does not comprise (I), where the composition does not comprise 2-hexyl-4-vinyl-1,3-dioxolane. R 3, R 4=H or 1-15C organic group optionally containing 1-3 O atoms, preferably H or saturated or unsaturated, aromatic or aliphatic, branched or unbranched, cyclic or linear, bridged or unbridged 1-15C group (optionally substituted by 1-3 alkyl, alkenyl and/or 1 or 2 OH, or R 3+ R 4=ring containing 5-8C atoms and optionally 1 or 2 double bonds and/or optionally 1-3 O atoms (optionally substituted by at least 1 branched or unbranched, bridged or unbridged alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, arylalkyl, alkoxyalkyl or alkoxyaryl) groups, and R 3and R 4comprise 3-30C atoms, or R 1, R 2=H or Me, preferably H, provided that: when a carbon-carbon single bond is present in position 3 to position 4 of R 4, then R 4is 4-15C alkyl (optionally branched and optionally contains >= 1-2 double bonds) or when R 3is not hydrogen, then R 4is 2-15C alkyl (optionally branched and optionally contains >= 1-2 double bonds).
