Racemic 4-[13C]catechin 14 has been synthesized in ten steps starting from potassium [13C]cyanide. The intermediate chalcone 9 was formed by acylation of the benzylated phloroglucinol 7 with the caffeic acid synthon 6, using the trifluoroacetic mixed anhydride. The flavonoid skeleton was then obtained by previously described reactions such as the reduction of chalcone 9 and dihydroxylation of flavene
外消旋 4-[13C] 儿茶素 14 已从 [13C] 氰化钾开始,分十步合成。中间体查耳酮 9 是通过使用三氟乙酸混合酸酐将苄基化间苯三酚 7 与咖啡酸合成子 6 酰化而形成的。然后通过先前描述的反应获得类黄酮骨架,例如查耳酮 9 的还原和黄酮 11 的二羟基化。这种 [13C] 标记的多酚应该被证明是人类生物学研究的有用工具。
