The present invention relates to a method for the stereo selective production of a trans-diol or a cis-diol or a hydroxyketone comprising the step(s) (i) conversion of a trans-diol or a cis-diol to a hydroxyketone and/or (ii) conversion of a hydroxyketoneto a cis-diol or a trans-diol, catalyzed by an enzyme, which is encoded by a nucleic acid sequence of SEQ ID NO: or wherein the enzyme comprises an amino acid sequence of SEQ ID NO: 2. The present invention also relates to the use of an enzyme encoded by a nucleic acid sequence of SEQ ID NO: 1 or wherein the enzyme comprises an amino acid sequence of SEQ ID NO: 2 for the conversion of a trans-diol to a cis-diol or for the conversion of a trans-diol or a cis-diol to a hydroxy ketone and/or the conversion of a hydroxyketone to a trans-diol or a cis-diol.

Biotechnological production of diols

The present invention primarily relates to the use of one or more stereoisomers of the compound of formula (I) as described herein for modifying and/or enhancing the olfactory impression of one or more fragrances with a lily of the valley scent. The invention further relates to a new mixture comprising or consisting of one or more stereoisomers of the compound of formula (I) as described herein and two or more stereoisomers of the compound of formula (II) as described herein with a weight ratio of the stereoisomers of the compounds of formula (II) as described herein, fragrance compositions comprising or consisting of a mixture as described herein, perfumed products containing mixtures or fragrance composition as described herein, and a process for modifying and/or enhancing the lily of the valley scent of a compound of formula (II) as described herein, respectively for preparing a perfumed product as described herein.

Use of ambrocenide&#xae; for intensifying a lily of the valley scent

The present invention relates in particular to a mixture comprising the compound of formula (Ia) as described herein, wherein the mixture is free or essentially free of the compound of formula (Ib) as described herein, preferably of the compounds of formulae (Ib) and furthermore (Ic) and/or (Id) as described herein. The invention further relates to a method for manufacturing said mixture, fragrance substance compositions containing or consisting of said mixture, perfumed products containing said mixtures or fragrance substance compositions, and various methods and uses for imparting, modifying and/or enhancing certain odour notes.

Blends containing enantiomerically pure Ambrocenide&#xae;

Suggested is a perfume composition, comprising

Perfume composition

The present invention relates to depot preparations for the targeted release of an aldehyde together with two carboxylic acids, where the released aldehydes are organoleptic substances, specifically fragrances or flavorings, and these depot preparations are prepared by reacting aldehydes with carboxylic anhydrides.

Depot preparations

Mixtures are described which comprise or consist of 3-(4-methylcyclohex-3-enyl)butyraldehyde (limonenal) and (4aR,5R,7aS,9R)-octahydro-2,2,5,8,8,9a-hexamethyl-4H-4a,9-methanoazuleno(5,6-d)-1,3-dioxole (Ambrocenide&#xae;), the weight ratio of limonenal to Ambrocenide&#xae; being in the range from 150:1 to 2500:1.

Mixtures of 3-(4-methylcyclohex-3-enyl)butyraldehyde and Ambrocenide&#xae; and corresponding uses and methods

The invention relates to a compound of the formula (VII) to an odoriferous substance or aroma composition comprising such a compound, and to a perfumed or aromatized product comprising such a compound. The invention furthermore relates to the use of a compound of the formula (VII) as an odoriferous substance and/or for improving fixation of an odoriferous substance or aroma composition. The invention moreover relates to a method for producing a compound of the formula (VII), to a method for producing a precursor of the compound of the formula (VII) and to the precursor itself. It moreover relates to a method for producing, enhancing or modifying a sandalwood odor in a mixture.

6-methyl-4-(2',2&#x2032;,3&#x2032;-trimethyl-3&#x2032;-cyclopenten-1&#x2032;-yl)-2-cyclohexen-1-ol as sandal odoriferous substance

A compound of formula (Ia) or (Ib), wherein in each of formulae (Ia) and (Ib) Rand R, independently of one another, are H or CH, and the use thereof as a sandalwood fragrance.

Sandal fragrances

The invention relates to novel alicyclic esters, methods for the their preparation, their use as fragrances and also perfumed products and fragrance mixtures containing the compounds according to the invention.

Alicyclic esters having a musky smell

Lower alkyl- and lower alkylidene-substituted, saturated or unsaturated cyclohexadecanones are grand fragrances with muscone note with which perfumes with new odor notes can be prepared.

Macrocyclic ketones

The present invention relates to novel macrocyclic compounds, and to their preparation and use in perfumes. Specifically, the present invention relates to novel 1,4-dioxacycloalkan-2ones and 1,4-dioxzcycloaken-2-ones.
