Abstract
The present invention relates to the perfumery industry. It concerns more particularly an alcohol, ester, ether or ketone derivative having a spiro-type skeleton, the latter being substituted by short alkyl groups. The invention also relates to the use of the invention compounds as perfuming ingredients, able to impart a woody and/or aromatic, as well as to the perfumed articles or perfuming compositions comprising as active ingredient a compound of formula (I).
Claims22
A composition comprising, as perfuming ingredient, at least one compound of formula
- wherein the index m represents 0 or 1;
- R represents a hydrogen atom, or a methyl or acetyl group;
- R1, R2 and R4 represent a hydrogen atom or a methyl group;
- R3 represents a hydrogen atom, or a methyl or ethyl group;
- two, three or four of all the R1, R2, R3 and
- R4 representing simultaneously a group containing at least a carbon atom;
- and
- the wavy and doffed lines represent a double bond, in which case n represents 0;
- or
- the wavy line represents a single bond, in which case the index n represents 1;
- and the dotted line represents a single or double bond;
- in the form of any one of its optical isomers or diastereomers or of a mixture thereof, and a perfume base.
A compound of formula (I)
- wherein the index m represents 0 or 1;
- R represents a hydrogen atom, or a methyl or acetyl group;
- R1, R2 and R4 represent a hydrogen atom or a methyl group;
- R3 represents a hydrogen atom, or a methyl or ethyl group;
- two, three or four of all the R1, R2, R3 and
- R4 representing simultaneously a group containing at least a carbon atom;
- and
- the wavy and dotted lines represent a double bond, in which case n represents 0;
- or
- the wavy line represents a single bond, in which case the index n represents 1;
- and the dotted line represents a single or double bond;
- in the form of any one of its optical isomers or diastereomers or of a mixture thereof, provided that 2,8 dimethyl spiro[5,5]undec-8-en-1-one, 2,9-dimethyl spiro[5,5]undec-8-en-1-one, 1,9 dimethyl spiro[5,5]undec-8-en-1-ol, 1,8-dimethyl spiro[5,5]undec-8-en-1-ol, 1,7-dimethyl spiro[4,5]dec-7-en-1-ol, 1,8-dimethyl spiro[4,5]dec-7-en-1-ol, 8,9-dimethyl spiro[5,5]unddec-8-en-1-one and 7,8-dimethyl spiro[4,5]dec-7-en-1-one are excluded.
A composition of at least two compounds of formula (I):
- wherein the index m represents 0 or 1;
- R represents a hydrogen atom, or a methyl or acetyl group;
- R1, R2 and R4 represent a hydrogen atom or a methyl group;
- R3 represents a hydrogen atom, or a methyl or ethyl group;
- two, three or four of all the R1, R2, R2 and
- R4 representing simultaneously a group containing at least a carbon atom;
- and
- the wavy and dotted lines represent a double bond, in which case n represents 0;
- or
- the wavy line represents a single bond, in which case the index n represents 1;
- and the dotted line represents a single or double bond;
- in the form of any one of its optical isomers or diastereomers or of a mixture thereof, provided that the compositions consisting of 2,8-dimethyl spiro[5,5]undec-8-en-1-one and 2,9-dimethyl spiro[5,5]undec-8-en-1-one, or 1,9-dimethyl spiro[5,5]undec-8-en-1-ol and 1,8-dimethyl spiro[5,5]undec-8-en-1-ol, or 1,7-dimethyl spiro[4,5]dec-7-en-1-ol and 1,8-dimethyl spiro[4,5]dec-7-en-1-ol are excluded.
