Oldfield, Mark F.,Chen, Lirong,Botting, Nigel P.
, p. 1266 - 1271 (2008/04/12)
A facile synthesis is described for [3,4,1′-13C 3]genistein for use as an internal standard in isoflavone analysis by mass spectrometric methods. Ethyl 4-hydroxy[1-13C]benzoate was first prepared from the reaction of dieth

Page 71-72, (2010/02/08)
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.

The syntheses of (17O)phenol from (17O)water, (18O)phenol from (18O)water, (1-13C)-phenol and (4-13C)phenol from (2-13C)acetone and (2-13C)phenol and (3-13C)phenol from (1-13C)acetone with high isotopic enrichment are described.The labelled phenols are converted into their corresponding L-tyrosines by the bacterium Erwinia herbicola.A full analysis of the 1H and 13C NMR spectra of phenol and L-tyrosine is reported.
