The present invention relates to the field of organic synthesis and more specifically it concerns a process for preparing compound of formula (I) catalyzed by a nickel complex. The compound of formula (II) is also part of the invention.
The present invention relates to the use as perfuming ingredient of a compound of formula in the form of any one of its stereoisomers or a mixture thereof, and wherein each R
1
represents a hydrogen atom or a methyl group and at least one of said R
1
is a hydrogen atom; R
2
represents a linear or branched C
3-8
alkyl group or unsaturated groups; and R
3
represents a hydrogen atom or a methyl group; in particular to impart odor notes of the violet leaves type optionally together with green odor notes.
