Abstract
PURPOSE: To prepare 3-hydroxy-4-pyrone compound useful as a perfume enhancer of food and feed economically advantageously and safely, by reacting a furylcarbinol compound with a halogen in a simple process without using a peroxide.
CONSTITUTION: A furylcarbinol (F) of formula I: (R1 is H or 1W7C hydrocarbon group), e.g. furylmethyl-, furylhexyl- or furylbenzylcarbinol, is reacted with at least two molecules per one molecule of F of a halogen in the presence of an alcohol of the formula R2OH(R2 is 1W7C hydrocarbon group) and an alkaline substance, e.g. NaOH or KOH, in an anhydrous state, and heated at room temperature to refluxing one, thus giving a 3-hydroxy-4-pyrone compound of formula II.
