Preparation of ring tritiated and of aldehyde carbon 14 labeled 1 pyrenecarboxaldehyde

, : Preparation of ring tritiated and of aldehyde carbon 14 labeled 1 pyrenecarboxaldehyde. Journal of Labelled Compounds & Radiopharmaceuticals 22(10): 1023-1032

A short, direct, and efficient synthesis of very high specific-activity ring-tritiated 1-pyrenecarboxaldehyde is described. A novel aspect of this synthesis involves direct bromination of an aromatic pyrene system carrying an electron-withdrawing aldehyde group. Synthesis of 14C-labeled 1-pyrene-carboxaldehyde is also described. Each of these compounds was converted in one step into the correspondingly radiolabelled trans-1-(2'-methoxyvinyl)pyrene.
