Synthesis of selectively 13C-labelled benzoic acid for nuclear magnetic resonance spectroscopic measurement of glycine conjugation activity

The synthesis of [4-13C]benzoic acid (BA) labelled in a single protonated carbon, for use as a probe to measure glycine conjugation activity by nuclear magnetic resonance (NMR) spectroscopy, has been reported. The labelled compound was prepared

Synthesis and NMR spectroscopy of stable isotope-labelled phenols and L-tyrosines

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.
