## Abstract Isoxazole derivatives, 3‐sulfanilamido‐5‐methylisoxazole (I) and 3,3‐dimethyl‐1‐(5‐methyl‐3‐isoxazolylcarbonyl)‐urea (II), have been labelled with carbon‐14. The carbon‐14 label was incorporated into the C‐5 of the isoxazole ring to give (I) and (II) in 22.3% and 33.0% radiochemical yie
## Abstract A number of synthetic approaches are assessed to prepare allantoin labelled with ^14^C given certain requirements and technical limitations. A method that fulfils these criteria is described to achieve the synthesis of highly pure ^14^C‐labelled allantoin with the label introduced to th

## Abstract The 2‐carbon units, glycine and glyoxylate are combined by a mild reaction via the copper chelate of glycine. The resulting β‐hydroxy aspartic acid is converted to DL‐malic acid by means of hydroxylamine 0‐sulfonic acid. The overall yields are in the range of 35–50% in submillimolar pre
## Abstract A method for the synthesis of 5‐ethylorotic acid‐2‐^14^C (V), 5‐ethyluracil‐2‐^14^C (VI) and 5‐ethylytosine‐2‐^14^C (VIII) starting from thiourea‐^14^C with the specific activity of 30 mCi/mM has been described. The labelled compounds obtained show satisfactory chemical and radiochemica
