Abstract

We have developed large-scale efficient procedures for the conversion of commercially available [(13) C]- or [(2) H3 ,(13) C]methanol and (13) CO2 or (13) C-labeled bromoacetic acid to 2-(phenylthio)[1,2-(13) C2 ]-, [1-(13) C]-, and [2-(13) C]acetic acid. The resulting derivatives are versatile, chemically stable, and nonvolatile two-carbon labeling precursors. We have used the (13) C-isotopomers of 2-(phenylthio)acetic acid in the synthesis of (13) C-labeled acrylic acid, methacrylic acid, and trans-crotonic acid.

Keywords: 13C-labeled synthons; 2-(phenylthio)[1,2-13C2]acetic acid; stable isotope labeling.
