Abstract
The compound of formula 1 in which the wavy line represents a bond having a configuration of the type (Z) or (E), or a mixture of the two configurations; R1 represents a hydrogen atom, a C1 to C4 linear or branched alkyl radical, a methoxy or ethoxycarbonyl radical, or an aryl radical, and R2 represents a methyl or ethyl group, possess interesting organoleptic properties and can be advantageously used for the preparation of perfuming compositions to which it gives, in particular, a very natural connotation of the pear type.
Claims7
A method to confer, improve, enhance or modify the odor properties of a perfuming composition or a perfumed product, which method comprises the step of adding to said composition or product a compound of formula
- 6
- in which the wavy line represents a bond having a configuration of the type (Z) or (E), or a mixture of the two configurations;
- R1 represents a hydrogen atom, a C1 to C4 linear or branched alkyl radical, a methoxy or ethoxycarbonyl radical, or an aryl radical, and R2 represents a methyl or ethyl group.
Perfuming composition or perfumed article, comprising as active ingredient a compound of formula
- 7
- in which the wavy line represents a bond having a configuration of the type (Z) or (E), or a mixture of the two configurations;
- R1 represents a hydrogen atom, a C1 to C4 linear or branched alkyl radical, a methoxy or ethoxycarbonyl radical, or an aryl radical, and R2 represents a methyl or ethyl group.
Compound of formula
- 8
- in which the wavy line represents a bond having a configuration of the type (Z) or (E), or a mixture of the two configurations;
- R1 represents a hydrogen atom, a C1 to C4 linear or branched alkyl radical, a methoxy or ethoxycarbonyl radical, or an aryl radical, and R2 represents a methyl or ethyl group provided that 3-methyl-2-hexenyl acetate and 3-methyl-2-heptenyl formate are excluded.
