The present invention relates to compounds of formula (I) as herein defined, capable of releasing fragrant compounds in a controlled manner into the surroundings. The present invention is also concerned with a process for their production, and consumer products comprising them.

Organic compounds

Compounds according to formula I in the form of any one of its stereoisomers or a mixture thereof

The present invention refers to alkoxybenzaldehyde derivatives and precursors thereof. The invention further refers to perfume compositions and fragranced article comprising them.

Alkoxybenzaldehyde derivatives and precursors thereof

An enzyme-mediated method for the production of 3a-ethyl-6,6,9a-trimethyldodecahydronaphtho[2,1-b]furan, the products of said method, and uses of said products.

Enzyme mediated process

A method for making 2-oxygenated decalins, and products thereof.

Method of making 2-oxygenated decalins from isoprenoids using a squalene-hopene cyclase

Disclosed is a use of a compound of formula (I), a composition of matter comprising a compound of formula (I) and a consumer product comprising a compound of formula (I). 

Thioether precursors for fragrant ketones and aldehydes

The present invention refers to 3,7-dimethyloct-6-en-1-yl methyl carbonate and its use as fragrance ingredient. The invention further refers to fragrance compositions and fragranced articles including it.

The present invention refers to aryl beta diketones of the formula (I) 

Aryl beta diketones and their use as odorants

A compound of the formula (I) in which, independently, The compounds have the characteristic desirable odour qualities of the Damascone&#xae; molecules, but lack their disadvantageous skin sensitization effects.

Perfume ketones

A compound represented by the formula I whereinis indicating a double bond either at C4 or at C5, or single bonds,R, R, R, Rare independently selected from H or Me, andR, Rare independently selected from Me or Et,and wherein the compound is not 9-hydroxy-5,9-dimethyldec-4-enal or 9-hydroxy-5,9-dimethyldecanal. Said compounds are useful as perfume ingredients in personal care and household care products.

Organic compounds and their use as fragrance ingredients

A compound of formula I wherein R, R, Rand Rcan be independently selected from H or Me,n=0, 1,the dotted lines are indicating single bonds, or in case n=0 an isolated double bond at position 3', or in case n=1 an isolated double bond at position 3&#x2032; or 4&#x2032;,and the wavy bond is indicating an unspecified configuration of the adjacent double bond. Said compounds, as well as precursors capable to generate said compounds, are useful as fragrance ingredients.

Crotonates having use in perfumery

A liquid fragrance composition consisting essentially of:

A compound represented by the formula I Ris &#x2014;(CHR)&#x2014;(CHR)&#x2014;(CHR)&#x2014;CHO, with R, R, Rbeing independently selected from H or Me, and with m, n, o being independently selected from 0 and 1; Ris H or Me; and Ris a C3-C6 branched, linear or cyclic alkenyl residue. Said compounds are useful as perfume ingredients in personal care and household care products.

A fragrance precursor represented by the formula 1 wherein

A method of providing a fragrant odour to an application, comprising the addition thereto of at least one compound of the formula I wherein X and Y are independently selected from the group consisting of &#x2014;CRRR, &#x2014;NRRand &#x2014;OR, wherein Rto Rare selected from H and essentially hydrocarbon moieties that optionally comprise at least one oxygen, nitrogen or silicon atom, and Ris selected from essentially hydrocarbon moieties that optionally comprise at least one oxygen, nitrogen or silicon atom; and, A is an essentially hydrocarbon moiety that optionally comprises at least one oxygen, sulphur, nitrogen or silicon atom, with the proviso that the compound A-CHO is a fragrant aldehyde. The use of these compounds in laundry, household and personal care products confers a long-lasting freshness.
