Synthesis of [3,4,8-13C3]daidzein

The biological effects of the soy isoflavones have attracted considerable interest in recent years leading to numerous studies on dietary intake and epidemiology. Such studies require accurate and reproducible analytical methods. Herein we report the firs

SYNTHESIS OF 13C-LABELLED ESTROGEN ANALOGUES

There is provided a method of producing novel 13C-labelled estrogen analogues. The method preferably proceeds via an intermediate A or B or which is a mixture of (A) or (B): wherein a13C atom is located at one or more of positions 1, 2, 3 or 4 and wherein R is an optionally substituted alkane, alkene, alkyne or aryl group. Preferably R is -CH2Ph. An alternative preferred intermediate compound is 13C-resorcinol.
