## Syntheses of [I 3C ] and [14C]-labelled versions of angiotensin I1 receptor antagonist GR138950X, labelled in the imidazole carboxamide residue, are described. These involved preparation of an iodoimidazole substrate by a novel iododecarboxylation procedure, followed by cyanation with a mixture

## Abstract Several easy preparative scale (0.5–1.5 g) syntheses of deuterium labelled caffeine, theophylline and theobromine are described. Some new selective syntheses of theophylline and theobromine have been developed. Labelled xanthines are of great interest in qualitative or quantitative isot

## Abstract ^13^C‐, ^14^C‐ and ^15^N‐labelled ethylenethiourea was synthesized for NMR and radiotracer applications in metabolism and environmental fate studies. The products contained stable isotopes at 99% enrichment and the radiolabelled product had specific activity of 2.0 mCi/mmole.

## Abstract [^13^C‐carboxyl]Salicylic acid has been prepared by carbonation of 2‐benzyloxybromobenzene followed by reductive debenzylation. Deuterium and tritium labelled salicylic acid and ^2^H~2~/^13^C‐salicylic acid were prepared by reduction of the 3,5‐dibromo derivatives using Raney Ni‐Al. Deu

## Abstract Three stable isotope‐labeled ethylcyclopropanes have been synthesized in preparation for a mechanistic study of its fragmentation to methane and butadiene. Two tactical innovations have been used to deal with practical synthetic challenges posed by the very limited solubility of methylm
