(57) Abstract: In a process for producing a 3-alkylflavanonol derivative (1) in which a compound represented by the following general formula (2) is oxidized using hydrogen peroxide, a reaction is carried out by using an aqueous phase and an organic phase. Production method in the state of being separated into two phases. Embedded image [Wherein, R 1 represents a C 1-12 alkyl group, and R 2 and R 3 Represents an optionally substituted C 1-12 alkyl or alkoxyl group, a hydrogen atom, a hydroxyl group, a cyano group or a halogen atom.] [Effect] This is an industrially advantageous production method. |
