• the acidic medium with the aid of mineral acids such as sulfuric acid or hydrochloric acid
• acidic salts such as bisulfates, for example KHS0 4
• acidic earths such as diatomaceous earth, for. B. Filtrol.
• Suitable organic acids such as medium to strong acids of this type, are also suitable. Examples include alkanesulfonic acids, such as methanesulfonic acid, p-toluenesulfonic acid or picric acid.
• the reaction temperature is not critical. It is expediently 20-200 ° C, preferably 60-130 ° C. It is expediently higher when using weaker acids and lower when using stronger acids.
• the reaction is preferably carried out with the aid of an organic solvent, in particular an aromatic solvent.
• organic solvent in particular an aromatic solvent. Examples are benzene, toluene and xylene.
• a mixture of la: Ib is obtained in an approximate ratio of 15:85. Traces of the cis / cis and trans / cis isomers can also be detected in the mixture.
• the separation of the isomer mixture can be carried out in a conventional manner, e.g. B. by means of column chromatography or preparative gas chromatography. As can be seen further below, the isomers do not differ fundamentally in their organoleptic properties, so that the isomer mixture can be used for economic reasons.

• Practically pure I in the sense of the present invention should be understood to mean in particular synthetically produced I.
• the compounds I used according to the invention as fragrances and / or flavorings - in particular Ib [because of its greater diffusion and intensity] - are distinguished by fresh, green, spicy, very natural-looking, certain aspects of cassis buds and exotic fruits - such as mango, passion fruit , Guanabana - reminiscent of smells.
• the compounds can accordingly serve, for example, for perfuming or aromatizing products, such as cosmetics (soaps, salves, powders, toothpastes, mouthwashes, deodorants, shampoos, lotions, etc.), detergents or foods, luxury foods and beverages, the compounds preferably not used alone, but in the form of compositions with other fragrances or flavors.
• fragrance or flavoring compositions with a content of compounds I and their preparation in a manner known per se (addition of I to known fragrance or flavoring compositions or mixing of I with natural or suitable components of fragrance or flavoring positions synthetic compounds or mixtures) also forms the subject of the invention.
• fragrance compositions produced using compounds 1, in particular of the Chypre, Cologne, Muguet or generally floral and woody direction, are particularly spectacular due to their spectacular freshness and originality.
