## Abstract [2‐^14^C]5‐Allyl‐2′‐deoxyuridine was synthesized directly from [2‐^14^C]2′‐deoxyuridine using mercury, palladium, and 3‐chloropropene. [2‐^14^C]5‐Propyl‐2′‐deoxyuridine was obtained by hydrogenation of the [^14^C]5‐allyl‐2′‐deoxy‐uridine. Advantages of the synthetic method and its appli

A high-yield, relatively simple synthetic route leading to incorporation of l'C into the secondary position of the adamantane nucleus is described. The synthesis was achieved by the sequence shown in Figure 2. The key steps involved the introduction of a I4C label by diazome1hane-14C ring expansion
