The compounds of the formula …IMAGE… in which… a) the dashes denote the position of a single or double bond in positions 4 and 8 and of a single carbon-oxygen bond in position 1, the wavy lines define a C-C bond in the E or Z configuration if the bond in positions 4 and 8 is a double bond, and the symbols Z1 and Z2, taken conjointly, define a cyclic ketal or acetal group of the formula …IMAGE… in which the symbols R1 and R2, which may be identical or different, each represent an alkyl radical, with a linear or branched chain, containing from 1 to 6 carbon atoms, or one of these symbols represents a hydrogen atom and the other represents an alkyl radical defined as above;… or in which… b) the symbol Z1 represents an oxygen atom or an OH group, the dashes represent the position of a single or double bond in positions 4 and 8 and of a single carbon-oxygen bond (Z1 = OH) or double carbon-oxygen bond (Z1 = O) in position 1, the wavy lines represent a C-C bond in the E or Z configuration if the bond in positions 4 and 8 is a double bond, and the symbol Z2 represents an OR3 group, where R3 is an alkyl radical, with a linear or branched chain, containing from 1 to 6 carbon atoms, are useful as perfuming ingredients. They serve to impart spicy aldehyde notes to perfumes and perfumed products. 12-Pentyloxy-4,8-cyclododecadien-1-one, 12-isobutoxy-4,8-cyclododecadien-1-one and 12-(2,2-dimethylpropoxy)-4,8-cyclopentadecadien-1-one are mentioned by way of preferred compounds. …??A process for the preparation of the compounds of the formula (I) is also described.
