USE OF CAMPHOLENE DERIVATIVES AS AROMATIC INGREDIENTS IN PERFUMERY AND MANUFACTURING Russian patent published in 2012 - IPC C07C255/31 C07C43/303 C07C47/11 C07C47/225 C07C49/21 C11B9/00 

FIELD: chemistry.

SUBSTANCE: invention relates to campholene derivatives of general formula (I), a fragrant or aromatic flavouring composition and use thereof in perfumery to obtain perfumed bases and concentrates, as aromatic agents for producing flavouring compositions or products, as agents which mask smell and/or taste, including in a combination with other perfumery or aromatic ingredients, solvents and additives. In general formula (I) , R1, R2, R3, R4 and R5 each independently denote a hydrogen atom or a linear or branched C₁-C₅ alkyl or C₂-C₅ alkenyl group, - Y denotes CN, C(O)R₆ or a CR₆(OR_α)(OR_β) group, where R₆ denotes a hydrogen atom or a linear or branched C₁-C₅ alkyl or C₂-C₅ alkenyl group, and R_α and R_β simultaneously denote a linear or branched C₁, C₂, C₃, C₄ or C₅ alkyl or C₂, C₃, C₄ or C₅ alkenyl group, the - 5-member ring is saturated or contains a double bond between C3' and C4' in formula (I), and the side chain, if necessary, contains a double bond between C1 and C2 and/or between C3 and C4, under the condition that said derivative is not 3-methyl-6-(2,2,3-trimethyl-cyclopent-3-enyl)-hex-4-enal.

EFFECT: use of campholene derivatives to obtain perfumed bases and concentrates.
