Abstract: The present invention concerns a compound of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein n is 0 or 1; R and R?, independently from each other, represent a hydrogen atom or a C1-2 linear alkyl group provided that one of said groups represents a hydrogen atom and the other a C1-2 linear alkyl group; each R1, independently from each other, represents a hydrogen atom or a methyl group; and R2 and R3 represent, independently of each other, a C1-3 linear alkyl group; or R2 and R3, when taken together, represent a C4-5 linear, branched alkanediyl or alkenediyl. The use of compound of formula (I) as perfuming ingredients of floral type and the invention's compounds as part of a perfuming composition or of a perfuming consumer product are also part of the present invention.

Abstract: The present invention concerns compound of formula in the form of any one of its stereoisomers or a mixture thereof, and wherein the exocyclic dotted line represents a carbon-carbon single or double bond, and one endocyclic dotted to line represents a carbon-carbon single bond and the other endocyclic dotted line represents a carbon-carbon double bond; and R, R1 and R2 represent, independently from each other, a hydrogen atom or a C1-3 alkyl group; and their use in perfumery to impart odor notes of the green, floral type.

Abstract: The present invention relates to trans isomers of formula (I) in the form of any one of its stereoisomers or a mixture thereof, and wherein the bold and hatched lines indicate a relative or absolute configuration; and one dotted line represents a carbon-carbon single bond and the other a carbon-carbon double bond; and their uses as perfuming ingredients (e.g. to impart vetiver/rooty notes), e.g. in consumer products.

Abstract: The present invention relates to a process for making indenol esters or ethers from an ?-substituted cinnamic aldehyde derivative such as an acetal or an acylal. Said reaction is promoted by the use of strong mineral acids, sulphonic acids, acidic zeolites or Lewis acids.

Abstract: A substantially odorless aromatic amine trapping agent is used in a composition including perfume for the purpose of enabling the perfume and trapping agent to react chemically together spontaneously and reversibly to form a reaction product form which the perfume can be released. In the reaction product, the perfume may be protected against degradation, premature evaporation etc., with the perfume being releasable from the reaction product. In contrast to a pro-perfume, the reaction product formed the present invention is not used by being included as such in a mixture of perfumes or perfumed product, but instead the perfume and trapping agent are included in a mixture of perfumes or perfumed product where they react spontaneously in situ to form a transient reaction product for subsequent release of the perfume. The invention also provides a perfume composition including the trapping agent.
