## Abstract

The compounds of formula ##STR1## wherein symbol X designates a C.dbd.O (Ia) or C(CH.sub.3)--OC(O)CH.sub.3 (Ib) group and the dotted line indicates the location of a single or double bond in formula (Ia) and of a double bond in formula (Ib), are characterised by useful odor notes of the aromatic, fruity, even amber type and can as a result be advantageously used as active perfuming ingredients.

## Claims

### Claim 1

A method to confer, improve, enhance or modify the odor properties of a perfuming composition or a perfumed article, which method comprises adding to said composition or article a fragrance effective amount of a polycyclic ketonic compound of formula ##STR5## wherein symbol X designates a C.dbd.O (Ia) or C(CH.sub.3)--OC(O)CH.sub.3 (Ib) group and the dotted line indicates the location of a single or double bond in formula (Ia) and of a double bond in formula (Ib).

### Claim 2 (depends on 1)

A method according to claim 1, wherein compounds (Ia, b) are present in their isomeric form of formula ##STR6## wherein X designates a C.dbd.O (Ia) or C(CH.sub.3)--OC(O)CH.sub.3 (Ib) group and the dotted line indicates the location of a single or double bond in formula (Ia) and of a double bond in formula (lb).

### Claim 3 (depends on 2)

A method according to claim 2, wherein the compound of formula (Ia,b) is (1RS, 2SR, 7RS)-tricyclo[6.2.2.0.sup.2,7 ]dodec-9-en-3-one.

### Claim 4 (depends on 2)

A method according to claim 2, wherein the compound of formula (Ia,b) is (1RS, 2SR, 3RS, 7RS)-3-methyl-tricyclo[6.2.2.0.sup.2,7 ]dodec-9-en-3-yl acetate.

### Claim 5

3-Methyl-tricyclo[6.2.2.0.sup.2,7 ]dodec-9-en-3-yl acetate.

### Claim 6

Tricyclo[6.2.2.0.sup.2,7 ]dodecan-3-one.

### Claim 7

A perfuming composition or a perfumed article containing as an active perfuming ingredient a polycyclic ketonic compound of formula ##STR7## wherein symbol X designates a C.dbd.O (Ia) or C(CH.sub.3)--OC(O)CH.sub.3 (Ib) group and the dotted line indicates the location of a single or double bond in formula (Ia) and of a double bond in formula (lb).

### Claim 8 (depends on 7)

As a perfumed article according to claim 7, a soap, a detergent, a haircare product, a cosmetic preparation, a body or air deodorant or a household product.
