## Abstract The synthesis of four isotopomers of dopamine labeled with deuterium or tritium is reported. The ring labeled [2′,5′,6′‐^2^H~3~]‐, and [2′,5′,6′‐^3^H~3~]‐dopamine were obtained using acid catalyzed isotopic exchange between dopamine and heavy or tritiated water respectively. Two selecti

Abstract
Deprotonation of paraherquamide (1a) at C‐24 and subsequent deuteration (or tritiation) is described. The procedure afforded 24‐^2^H‐paraherquamide (1b) with 66% deuterium incorporation at C‐24. Modification of the deuteration procedure to allow the introduction of tritium resulted in the preparation of 24‐^3^H‐paraherquamide (1c) with specific activity 3.7 Ci/mmol.

## Abstract The synthesis of d, l, ‐12‐bromocamptothecin (**2d**) from camptothecin (**1**) is described. Reduction of the bromo derivative **2d** with tritium gas in the presence of palladium on carbon afforded d, l‐camptothecin 12‐^3^H having a specific activity of 29 Ci/mmol. A simpler labelling
## Abstract A mild exchange labeling procedure utilizing O‐deuterated or O‐tritiated t‐butanol with sodium catalysis afforded isotope exchange in the α‐hydrogen position of the amide N‐t‐butyl‐2‐(5‐benzyloxy‐6‐hydroxymethyl‐2‐pyridyl)‐2‐hydroxy‐acetamide, thereby extending the utility of this appro
## Abstract Deuterium and tritium labeled 4,5′,8‐trimethylpsoralen (), psoralen (), and angelicin (), have been prepared by D~2~O and T~2~O exchange with specific activities of 228‐253 mCi/mmol. Tritium labeled 4,5′,8‐trimethylpsoralen () with a specific activity of 17.6 Ci/mmol was prepared by cat
