| abstract |
The invention relates to carbonyl compounds of the general structure (I) where the rest R<1> is hydrogen or an alkyl group with between 1 and 5 carbon atoms, the rests R<2> and R<3> independently of each other are hydrogen or an alkyl group with between 1 and 3 carbon atoms and one of the positions C-1/C-2, C-2/C-3 or C-1/C-6 has a C=C double bond, and the rest R<4> is either hydrogen or, if the C=C double bond is situated in position C-2/C-3, hydrogen or an alkyl group with between 1 and 3 carbon atoms. The above compounds are characterized by interesting fragrance notes of great intensity and are suitable for use as fragrances in, for example, cosmetic preparations, technical products or perfumed spirits. |
