本文中,我们报告了一种合成方法,该方法通过使用碳酸钠/过氧化氢,通过Algar-Flynn-Oyamada反应(AFO)对5-取代的黄酮醇进行了改进,具有中等至高收率的一系列5-取代的黄酮醇。阐明了AFO反应的机理。LCMS分析和原位1 H NMR分析表明,在碱性碱/过氧化物条件下,环氧化物参与了从查尔酮到黄酮醇和/或金酮的转化。

chalcone derivatives and by examining the structure-activity relationships on the inhibition of rat lens aldosereductase as well as on antioxidant effects. A series of 35 flavonoid derivatives were synthesized by Winget's condensation, oxidation, and reduction of appropriate acetophenones with appropriate benzaldehydes. The inhibitoryactivity of these derivatives on rat lens aldosereductase and their
