双黄酮类化合物的合成研究(Ⅴ)——0-六甲基Brackenin及其类似物的合成
Study on the Synthesis of Some New Biflavonoids (Ⅴ) ——Total Synthesis of 0-Hexamethyl Brackenin
【摘要】 <正> Brackenin(Ia)是迄今为止从自然界中分离得到的第1个也是唯一的1个双二氢查耳酮,它的合成尚未见报道。为探索这类化合
【Abstract】 O-Hexamethyl brackenin ( I b) was first successfully synthesized by using resorcinol as starting material. According to the same synthetic route, the other two dimeric dihydrochalcones ( I c, I d) were also synthesized.
