A process for producing rotundone from α-guaiene, in particular by oxidation of the C(3) position, wherein the α-guaiene is produced from a precursor by a sesquiterpene synthase. The sesquiterpene synthase is produced in a microorganism.

Production of guaiene and rotundone

An enzyme-mediated method for the production of acetates as defined by formula (I), the products of said method, and uses of said products.

Conversion of farnesylacetone to homofarnesylacetate by baeyer-villiger monooxygenase

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

Organic compounds

A process for producing rotundone from &#x3b1;-guaiene, in particular by oxidation of the C(3) position, wherein the &#x3b1;-guaiene is produced from a precursor by a sesquiterpene synthase. The sesquiterpene synthase is produced in a microorganism.

The regio-selective functionalization of a dialkyl benzene compound wherein the ratio of the compound functionalized at position (a) to the compound functionalized at the position (b) is at least 70:30, more particularly at least 80:20, still more particularly at least 85:15, and still more particularly at least 90:10, characterised in that the substituent R is an isobutyl group.

Process of forming 2-(4-isobutyl-2-methylphenyl) propanal

An aryl-substituted alkanal compound having a molecular weight of less than 300 g/mol and which bears a substituent on the aryl ring ortho to a substituent bearing the aldehyde functionality. Said compounds are useful as perfume ingredients in personal care and household care products.

Process involving cross metathesis of olefins

meta-Substituted 3-phenylpropanal derivatives useful in providing watery-marine, floral-aldehydic notes.

A process of forming methoxymelonal comprising the steps of treating a solution of citronellene to ozonolysis, and hydrogenating the product formed to provide methoxymelonal.

Process for the preparation of methoxymelonal

A direct acid catalyzed intermolecular electrocyclic rearrangement process for the preparation of linear and cyclic homoallylic ester and amides. A one step intermolecular electrocyclic rearrangement process includes the step of reacting a beta, gamma-unsaturated aldehyde or ketone, in which the beta, gamma-unsaturation is not part of an aromatic ring, with another aldehyde or a secondary aldimine in the presence of an acid.
