The synthesis of multiply 13C-labelled plant and mammalian lignans as internal standards for LC-MS and GC-MS analysis
Fryatt, Tara,Botting, Nigel P.
, p. 951 - 969 (2005)
The syntheses of multiply 13C-labelled derivatives of the two mammalian lignans, enterolactone and enterodiol, and two of their plant lignan precursors, secoisolariciresinol and matairesinol, are described. Three 13C atoms were incorporated into each lignan using potassium [ 13C]cyanide as the source for all of the 13C atoms. The compounds were prepared for use as internal standards in the LC-MS and GC-MS analysis of lignans. Copyright

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.
