| abstract | (57) Abstract: 4-Hydroxy-6-methyl-3- (4-methyl-2-pentenoyl) -2-pyrone and 4-hydroxy-6-methyl-3- (4-methylpentanoyl) -2 -To provide a method for producing pyrone. SOLUTION: 3-acetyl-4-hydroxy-6-methyl-2-pyrone and isobutyraldehyde are represented by the formula R 1 R 2 N H is reacted at −5 to 25 ° C. in the presence of a secondary amine represented by H (wherein R 1 and R 2 each represent a linear C1-C4 alkyl group) and molecular sieves. Process for producing hydroxy-6-methyl-3- (4-methyl-2-pentenoyl) -2-pyrone and reducing 4-hydroxy-6-methyl-3- (4-methylpentanoyl) -2 to reduce the compound -The active ingredient of the harmful arthropod controlling agent or its intermediate can be advantageously produced by the method for producing pyrone. |
