The present invention relates to a production method, and more specifically, it is a production method for methyldamascone, which is characterized by subjecting arrangementols obtained by oxidizing cis-8-methylonols to rearrangement dehydration or rearrangement dealcoholization using an acidic substance as a catalyst.

Arrangeols referred to in the present invention are novel substances described at the end of literature having the following chemical formula 1, and can be used to impart flavor and improve the quality of popular products such as cigarettes, tea, and alcoholic beverages. Also, methyldamascone, which is obtained from Arrangeols and is represented by the following chemical formula 2, is a substance that is effective not only for improving the flavor imparting quality of Akebono products, but also as a flavoring agent, like Arrangeols. Cis-8-methylonol (chemical formula 3), which is used as a raw material in the production of rangeols, can be produced from 8-ionone (chemical formula 4) by a Grignard reaction or other suitable method.

That is, trans-8-methylonol can be easily converted into cis-8-methylonol in high yield by photochemical reaction in the presence of conventional photosensitizers such as 1-acetonaphthone, 2-acetonaphthone, 1-naphthylphenyl ketone, triphenylene, and benzophenone. It can be changed. cis8-
Methods for oxidizing methylonol to arangeols include photochemical oxidation using oxygen in the presence of a photosensitizer, or fermentation using singlet oxygen generated from hydrogen peroxide and sodium hypochlorite, etc. is preferred. Since peroxide may be generated during oxidation, it is preferable to treat the oxidized product with a suitable reducing agent such as lithium aluminum hydride or boron hydride. Any photosensitizer may be used in the photochemical oxidation, including rose bengal, methylene blue,
Hematoporphin and the like are preferred.

In addition, in the case of oxidation, cis-8-methylonol may be isolated, but cis-8-methylonol may be isolated from trans-8-methylonol.
- Even if the photosensitizer used for the rearrangement to methylonol is not removed, the oxidation reaction will not be affected. The rearrangement-dehydration or rearrangement-dealcoholization of rangeols to methyldamascone easily proceeds in the presence of a catalyst, and examples of such catalysts include acidic substances such as inorganic acids, organic acids, and cation exchange resins. It is preferable to dissolve the acidic substance in an aqueous solution. (R is hydrogen or a lower alkyl group) Cis B-methylonol as a raw material for rangeols refers to methyl ether, ethyl ether, propyl ether and other alkyl ethers of cis 8-methylonol.

When such ethers of cis-8-methylonol are used as raw materials, oxidation produces rangeols, namely corresponding monoethers such as rangeol monomethyl ether and rangeol monoethyl ether. Like arrangement all, these arrangement all can also be used to impart flavor to and improve the quality of food products. Furthermore, methyldamascone is produced by rearranging these rangeols in the presence of the same catalyst as mentioned above. In this case, the corresponding alcohol is eliminated by the rearrangement reaction. This will be explained below using examples.
