## Abstract

The present invention relates to compounds of formula (I) that are useful as perfuming ingredients of the fruity type. Formula (I) is in the form of any one of its stereoisomers or of a mixture thereof, wherein R1 represents a C1-3 alkyl or alkenyl group, R2 represents a methyl or ethyl group, R3 represents a C1-4 alkyl or alkenyl group, and the compound (I) has from 8 to 12 carbon atoms.

## Claims

### Claim 1

A compound of formula
in the form of any one of its stereoisomers or of a mixture thereof, and wherein R1 represents a C3 alkyl group, R2 represents a methyl group, R3 represents a C3-4 alkyl group, and said compound (I) has from 10 to 11 carbon atoms, wherein the compound of Formula (I) provides an odor having fruity and/or floral notes devoid of a herbaceous note.

### Claim 2 (depends on 1)

The compound of claim 1, wherein the compound is (−)-propyl (2S)-2-(isobutyryloxy)propanoate.

### Claim 3 (depends on 1)

The compound of claim 1 which has 10 carbon atoms wherein R1 represents a C3 alkyl group and R3 represents a C3 alkyl group.

### Claim 4

A compound of formula:
in the form of any one of its stereoisomers or a mixture thereof, and wherein R1 represents a C3 alkyl group, R2 represents a methyl group, and R3 represents a C4 alkyl group, wherein the compound of Formula (I) provides an odor having fruity and/or floral notes devoid of a herbaceous note.

### Claim 5
