施には望ましい。 In the present invention, the order of addition of reaction reagents has an important effect on the structure of the hydroxychalcone and its derivatives produced. That is, Example 1
As shown in , when haloform, acetophenone, or a derivative thereof is added in this order to an alkaline aqueous solution of phenol containing cyclodextrin and reacted, 4-hydroxychalcone or a derivative thereof is obtained with almost 100% selectivity. However, when adding a reaction reagent, the reaction rate of the reaction between the previously added different reaction reagent and phenol or a reaction intermediate derived from it is 50 to 100%.
Preferably 95-100% is desirable for practicing the present invention.

生成の選択性の向上は達成される。 As the cyclodextrin, both α-cyclodextrin and β-cyclodextrin can be used. In order to obtain hydroxychalcone or its derivatives with a selectivity close to 100%, the amount of cyclodextrin added is preferably 0.5 or more in terms of molar ratio to haloform and acetophenone or its derivatives present in the reaction system. Even with the following amounts of cyclodextrin used, improved selectivity in the production of hydroxychalcone or its derivatives is achieved.

クロデキストリンは完全に再使用にたえる。 Cyclodextrin does not change during the reaction and can be reused as is after the reaction. After the reaction, when the reaction system is made acidic, cyclodextrin precipitates due to decreased solubility. More than 80% of the cyclodextrin can be recovered using this simple method, and the recovered cyclodextrin can be completely reused.
