Claims10
A compound of formula (I) in the form of any one of its stereoisomers or mixture thereof
- wherein
- R1 is selected from C1-C3 alkyl;
- R2 is a hydrocarbon residue comprising up to 10 carbon atoms;
- R3 and R4 are independently selected from hydrogen and methyl with the proviso that R3 or R4 is methyl;
- and
- the dotted line together with the carbon-carbon bond forms a single bond or a double bond.
A flavour or fragrance composition comprising a compound of formula (I) in the form of any one of its stereoisomers or mixture thereof
- wherein
- R1 is selected from C1-C3 alkyl;
- R2 is a hydrocarbon residue comprising up to 10 carbon atoms;
- R3 and R4 are independently selected from hydrogen and methyl with the proviso that R3 or R4 is methyl;
- and
- the dotted line together with the carbon-carbon bond forms a single bond or a double bond.
A fragranced article comprising a compound of formula (I) in the form of any one of its stereoisomers or mixture thereof
- wherein
- R1 is selected from C1-C3 alkyl;
- R2 is a hydrocarbon residue comprising up to 10 carbon atoms;
- R3 and R4 are independently selected from hydrogen and methyl with the proviso that R3 or R4 is methyl;
