Abstract
(3S,5R)-3,8-dimethyl-5-(prop-1-en-2-yl)-octahydroazulen-1-ols, their use as flavour or fragrance ingredient, and a process of their production by oxidation in the presence of laccase.
Claims11
A process of producing a compound of formula (I)
- wherein the dotted line together with the carbon-carbon bond between C-3a and C-8a represents a double bond and the dotted line together with carbon-carbon bond between C-8a and C-8 represents a single bond;
- or
- the dotted line together with the carbon-carbon bond between C-8 and C-8a represents a double bond and the dotted line together with carbon-carbon bond between C-3a and C-8a represents a single bond, and C-3a is (S)-configurated,
- by reacting laccase and a material comprising α-guaiene and/or α-bulnesene in the presence of an oxygen source.

A compound of formula (I)
- wherein the dotted line together with the carbon-carbon bond between C-3a and C-8a represents a double bond and the dotted line together with carbon-carbon bond between C-8a and C-8 represents a single bond.
A flavour or fragrance composition comprising a compound of formula (I)
- wherein the dotted line together with the carbon-carbon bond between C-3a and C-8a represents a double bond and the dotted line together with carbon-carbon bond between C-8a and C-8 represents a single bond;
- or
- the dotted line together with the carbon-carbon bond between C-8 and C-8a represents a double bond and the dotted line together with carbon-carbon bond between C-3a and C-8a represents a single bond, and C-3a is (S)-configurated,
- obtainable through the process by reacting patchouli oil or a light fraction of patchouli oil and laccase in the presence of an oxygen source.
