This application is a national stage application under 35 U.S.C. § 371 of International Patent Application PCT/EP2017/065072, filed 20 Jun. 2017, which claims the benefit of EP patent application 16175671.3, filed 22 Jun. 2016.
The present invention relates to the field of perfumery. More particularly, it concerns 1-acetyl derivatives of cyclododecatriene as defined below and their uses as perfuming ingredients. Therefore, following what is mentioned herein, the present invention comprises also the invention compound as part of a perfumed consumer product.
To the best of our knowledge, the invention's compounds, as such are known (see J. Graefe et al, in Tetrahedron 1970, 26, 2677,) and reported as chemical products only. Graefe does not report or suggest any organoleptic properties of the compounds of formula (I), or any use of said compounds in the field of perfumery.
We have now surprisingly discovered that a compound of formula
in the form of any one of its stereoisomers or a mixture thereof, and wherein one dotted line represents a carbon-carbon single bond and the other a carbon-carbon double bond; and
R represents a hydrogen atom or a C1-4 alkyl or alkenyl group;
