## Claims

### Claim 1

A compound of the formula (I)
wherein
R and R1 are independently selected from hydrogen and methyl;
the bond between C-3 and C-4 and the bond between C-5 and C-6 are single bonds; or
the dotted line together with the bond between C-3 and C-4 and the bond between C-5 and C-6 represent double bonds,
the compound of formula (I) being characterized by its orris odor.

### Claim 2 (depends on 1)

The compound according to claim 1 wherein the dotted line together with the bond between C-3 and C-4 and the bond between C-5 and C-6 represent double bonds, and both double bonds are in (E)-configuration.

### Claim 3 (depends on 2)

The compound according to claim 2 selected from (3E,5E)-5-tert-butylocta-3,5-dien-2-one, (3E,5E)-5-(tert-pentyl)octa-3,5-dien-2-one, and (3E,5E)-5-(tert-butyl)-7-methylnona-3,5-dien-2-one.

### Claim 4 (depends on 1)

The compound according to claim 1 selected from the group consisting of 5-tert-butylocta-3,5-dien-2-one, 5-(tert-pentyl)octa-3,5-dien-2-one, 5-(tert-butyl)-7-methylnona-3,5-dien-2-one, 5-tert-butyloctan-2-one, 6,6-dimethyl-5-propyloctan-2-one, and 5-tert-butyl-7-methylnonan-2-one.

### Claim 5

A method of using a compound of formula (I) as a fragrance ingredient, comprising a step of utilizing the compound of formula (I) to form a fragrance
wherein
R and R1 are independently selected from hydrogen and methyl;
the bond between C-3 and C-4 and the bond between C-5 and C-6 are single bonds; or
the dotted line together with the bond between C-3 and C-4 and the bond between C-5 and C-6 represent double bonds,
the compound of formula (I) being characterized by its orris odor.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the compound of formula (I) wherein the dotted line together with the bond between C-3 and C-4 and the bond between C-5 and C-6 represent double bonds, and both double bonds are in (E)-configuration.

### Claim 7

A fragrance composition or a perfumed product comprising a compound of formula (I)
wherein
R and R1 are independently selected from hydrogen and methyl;
