The ring-fission metabolites of epicatechin, 5-(3,4-dihydroxybenzyl)dihydrofuran-2(3H)-one M6 and 3-methylated M6, were prepared from 3,4-dihydroxybenzaldehyde and furan-2(5H)-one using two new concise methods in excellent yields (three or two steps in 40–60% overall yield).
表儿茶素、5-(3,4-二羟基苄基)二氢呋喃-2(3H)-one M6 和 3-甲基化 M6 的裂环代谢物是由 3,4-二羟基苯甲醛和呋喃-2(5H)-one 制备的两种新的简洁方法,产量极佳(三到两步,总产量为 40-60%)。
