Die Erfindung betrifft eine neue Riechstoffkomposition.
Durch die NL-OS 64 12 168 ist es bereits bekannt, daß 6-(2-Methyl-l-propenyl)-2,4,6-trimethyl-2H-5H-dihydropyran
sowie dessen Isomere einen vorherrschenden Rosendurft in Verbindung mit einem geringeren
Geraniendurft besitzen. Aus der genannten NL-OS ergibt sich weiter, daß Dihydropyrane nicht generell als
Duftstoffe geeignet sind. So wird z. B. angegeben, daß das 6-Isobutyl-2,4-dimethyl-5,6-di/iydro-2H-pyran als
Parfüm unbrauchbar ist.
Überraschenderweise wurde nun gefunden, daß sich bestimmte Pyranderivate gut als Riechstoffe eignen.
Gegenstand der Erfindung ist eine Riechstoffkomposition
enthaltend eine oder mehrere Verbindungen der Formeln

Die Verbindungen, die einzeln und in Mischung verwendet werden können, besitzen eine sehr hervorstechende,
durchdringende grüne Geruchsnuance mit einem klaren Anflug von Geranie und können in
verschiedenen Kompositionen eingesetzt werden. So verleihen sie blumenähnlichen Kompositionen eine
natürliche, grüne Note von Geranie, Rose, Jasmin, Hyazinthe, Flieder und Veilchen. Für solche Zusammensetzungen
genügen sehr geringe Mengen von 0,1—0,5%. Höhere Dosierungen von 0,5—2% verleihen
Kompositionen eine Fougere-, Tabak-, Chypre-Note oder andere Phantasie-Noten.
Die für die erfindungsgemäße Riechütoffkomposition benötigten Verbindungen lassen sich gemäß der US-PS
24 52 977 herstellen.
