[4-13C]-porphobilinogen 1a, [3-13C]-porphobilinogen 1b and [11-13C]-porphobilinogen 1c are prepared from [1-13C]-3-(tetrahydropyran-2′-yloxy)-propionaldehyde 2a, methyl [4-13C]-4-nitrobutyrate 3b and [1-13C]-isocyanoacetonitrile 5c, respectively. The building blocks 2, 3 and 5 can be prepared efficiently in any isotopomeric form. Via base-catalyzed condensation of these building blocks porphobilinogen can be enriched with 13C and 15N stable isotopes at any position and combination of positions.
