USE OF CAMPHOLENIC DERIVATIVES AS FRAGRANT INGREDIENTS IN PERFUMERY AND FLAVOURING.

摘要

This invention relates to campholenic derivatives of general formula (I) wherein Rl, R2, R3, R4 and R5 represent, each independently, a hydrogen atom or a linear or branched C1-C5 alkyl or C2-C5 alkenyl group, Y represents a CN, a C(O)R6 or a CR6 (ORα) (ORβ) group, wherein R6 represents a hydrogen atom or a linear or branched C1-C5 alkyl or C2-C5 alkenyl group, and Rα and Rβ represent simultaneously a linear or branched C1, C2, C3, C4 or C5 alkyl or C2, C3, C4 or C5 alkenyl group and can form together a cycle, the 5-membered ring is saturated or has a double bond between C3 ' and C4 ' in formula (I), and the side chain, optionally, has a double bond between C1 and C2 and/or between C3 and C4, provided that the derivative is not 3-methyl-6- (2, 2, 3-trimethyl-cyclopent-3-enyl) -hex-4-enal; and their use as fragrant or flavouring agent.
