Cycloalkane aldehydes, method for preparing same, and use thereof in the perfume industry

The invention relates to a compound of general formula I represented below: wherein: R1, R2 and R3 each independently represent a hydrogen atom or saturated or unsaturated, branched or non-branched C1 to C5 alkyl group;m is an integer between 1 and 4;n is an integer between 2 and 4; characterized in that the ring is saturated and comprises from 5 to 8 carbons, that the total number of carbons of the ring and of the radicals R1, R2 and R3 is between 7 and 11 and it being understood that said compound of formula (I) is not: 6-cycloheptylidenehexanal4-(4-methylcyclohexylidene)-butanal4-(4-tert-butylcyclohexylidene)-butanal4-(3,3,5-trimethylcyclohexylidene)-butanal as well as a method of synthesizing said compounds, and their uses in perfumery.

Use of campholenic derivatives as fragrant ingredients in perfumery and flavouring

This invention relates to campholenic derivatives of general formula (I) Wherein R1, R2, R3, R4 and R5 represent, each independently, a hydrogen atom or a linear or branched C1-C5 alkyl or C1-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 C1-C5 alkenyl group, and Rα and Rβ represent simultaneously a linear or branched C1, C2, C3, C4 or C5 alkyl or 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.
