合成黄酮化合物一般常用的方法是Baker-Vakataraman重排法及二氧化硒氧化2′-羟基查尔酮法。 Fatma等曾报道,I_2/DMSO/H_2SO_4系统可使二氢黄酮脱氢生成黄酮。 我们利用I_2/DMSO/H_2SO_4系统,在100℃搅拌2.5小时或12小时,可以从某些2′-羟基查
Commonly used methods for the synthesis of flavonoids are the Baker-Vakataraman rearrangement and the 2’-hydroxychalcone oxidation of selenium dioxide. Fatma et al. Have reported that the I 2 / DMSO / H 2 SO 4 system can dehydrogenate flavonoids to flavones. We use I 2 / DMSO / H 2 SO 4 system, stirring at 100 ℃ for 2.5 hours or 12 hours, from 2’-hydroxy
