## Abstract The ringโ and sideโchainโ^14^Cโlabeled DLโ4,4โฒโpropylenediโ2,6โpiperazinediones (I) were synthesized from chloroacetic acidโ1โ^14^C in two steps and from DLโanalineโ1โ^14^C in six steps, respectively. The radiochemical yield for the ring labeling was 24.5%; for the sideโchain labeling i
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
