FIELD: chemistry.

SUBSTANCE: invention relates to novel compounds of general formula

that can be used in perfumery, cosmetics and in the production of detergents, an aromatic composition comprising, at least, one compound of general formula I, as an isomer or a mixture of isomers, an enantiomer or a mixture of enantiomers, either as a racemic mixture or as a diastereomer or a mixture of diastereomers, to the method of producing a compound of formula I, as well as the use of, at least, one compound of formula I as a flavouring and masking agent or an odour neutralizing agent. In formula I, R1, R2 and R3 are each independently a hydrogen atom or a saturated, branched or unbranched C₁-C₅alkyl group; m is an integer from 1 to 4; n is an integer from 2 to 4; the ring is saturated and contains from 5 to 8 carbon atoms, the total number of carbon atoms in the ring and the radicals R1, R2 and R3 is from 7 to 11. Herewith the compound of formula I is not: 6-cycloheptylidenehexanal, 4-(4-methylcyclohexylidene)-butanal, 4-(4-t-butylcyclohexylidene)-butanal, 4-(3,3,5-trimethylcyclohexylidene)-butanal.

EFFECT: improving the compound properties.
