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.
