概要
- 論文の詳細を見る
The reaction of flavanone with "2-pyrrolidone hydrotribromide" in tetrahydrofuran gave 3-bromoflavanone in a good yield. On the other hand, flavone was obtained in 97% yield when this reaction was carried out in dimethyl sulfoxide at 80 °C. Under the same conditions, most flavones were obtained from the corresponding flavanones in high purity and good yields.
