The present invention relates to the field of perfumery. More particularly, it concerns some derivatives of formula 5 in the form of any one of its stereoisomers or a mixture thereof, and wherein R1 represents a hydrogen atom, a C1-4 alkyl or alkenyl group, or a (CHR)2OH group, each R being a hydrogen atom or a methyl group; R2 represents a hydrogen atom or a 10 methyl, ethyl or n-propyl group; and R3 represents a hydrogen atom or a methyl group; as well as their use as perfuming ingredients. The present invention concerns also the compositions or articles containing said compounds.
The present invention pertains to pro-fragrances and relates to a pro-fragrance compound of the formula (I). Furthermore, the invention relates to compositions, a laundry product, a home care product, and an insect repellant, comprising the compound of formula (I). Also encompassed are a method for preparing the compound of formula (I) and uses of a compound of formula (I) for increasing the longlastingness of a fragrance, for increasing the stability and perception of a fragrance, and for improving the adhesion of a fragrance to textiles.
Suggested is a cosmetic compositions comprising
(a) a crosspolymer obtained from copolymerisation of at least two different polyols and at least one dicarboxylic acid and
(b) at least one fragrance.

A one-pot procedure is described for using alpha,beta-unsaturated aldehydes as olefin equivalents in the Diels-Alder reaction. The method combines the normal electron demand cycloaddition with aldehyde dienophiles and the rhodium-catalyzed decarbonylation of aldehydes to afford cyclohexenes with no electron-withdrawing substituents. In this way, the aldehyde group serves as a traceless control element
