Process for preparing gamma-pyrones |
| abstract |
The gamma-pyrones of formula I in which the symbols have the meaning given in Claim 1 are obtained by a simple and economic "one-pot" process by reaction of a furfuryl alcohol of formula III with at least 2 equivalents of a halogenated oxidising agent, in aqueous solution at a temperature of between -50 DEG and +50 DEG C, and then the reaction mixture is heated until hydrolysis of the intermediate formed is virtually complete. The gamma-pyrones obtained can be used as products which enhance flavour and fragrance in food and cosmetic preparations. <IMAGE> |
