A flexible synthetic method is presented, which allows all the key isoflavones (daidzein, genistein, glycitein, formononetin and biochanin A) to be prepared in 13C-labelled form via the same route, involving the thallium(III)-mediated oxidative rearrangement of a key chalcone intermediate. This method results in the incorporation of 13C atoms at the 2, 3 and 4 positions of the isoflavone skeleton. We also report the first syntheses of 13C-labelled versions of the daidzein metabolites, equol and ODMA. Copyright © 2009 John Wiley & Sons, Ltd.
提出了一种灵活的合成方法,该方法允许通过相同的路线制备所有关键的异黄酮(大豆苷、染料苷、甘草苷、福尔莫诺苷和生物苷A)13C标记形式,涉及锑(III)的氧化重排关键查尔酮中间体。这种方法导致在异黄酮骨架的2、3和4位上引入13C原子。我们还报告了大豆苷代谢物(等黄酮和ODMA)13C标记版本的首次合成。版权 © 2009 John Wiley & Sons, Ltd.
