Patent ID: 7589055

Claim:
A compound of the formula P—X—R (I) wherein: a) P represents a radical derived from an perfuming α,β-unsaturated ketone, aldehyde or carboxylic ester and is represented by formula in which R 1 represents a hydrogen atom, a C 1 to C 6 alkoxyl radical or a C 1 to C 15 linear, cyclic or branched alkyl, alkenyl or alkadienyl radical, optionally substituted by up to four C 1 to C 4 alkyl groups; and R 2 , R 3 and R 4 represent a hydrogen atom, an aromatic ring or a C 1 to C 15 linear, cyclic or branched alkyl, alkenyl or alkadienyl radical, optionally substituted by up to four C 1 to C 4 alkyl groups; two, or three, of the groups R 1 to R 4 can be bonded together to form a saturated or unsaturated ring having 6 to 20 carbon atoms and including the carbon atom to which said R 1 , R 2 , R 3 or R 4 groups are bonded, this ring being optionally substituted by up to four C 1 to C 4 linear or branched alkyl or alkenyl groups or by one C 3 to C 9 cyclic alkyl or alkenyl groups; and b) X represents a sulfur atom and R represents a cyclic, linear or branched alkyl, alkenyl or alkadienyl C 1 -C 5 hydrocarbon radical wherein the alkyl, alkenyl or alkadienyl C 1 -C 5 hydrocarbon radical is substituted with a Si(OR 5 ) 3 group, R 5 representing a C 1 -C 5 alkyl or alkenyl group; or X represents a OC(O)O functional group and R represents a cyclic, linear or branched alkyl, alkenyl or alkadienyl C 1 -C 5 hydrocarbon radical optionally substituted with a Si(OR 5 ) 3 group, R 5 representing a C 1 -C 5 alkyl or alkenyl group; said compound of formula (I) being in the form of a pure diastereomer or stereoisomer or in the form of any mixture of said isomers.
