11 C-Labeling: Intracyclic Incorporation of Carbon-11 into Heterocycles

Abstract : Labeling of heterocycles with carbon-11 is generally performed through peripheral functionalizations and more scarcely inside heterocyclic core. Such less common approach usually requires preliminary multi-step synthesis of reactive species. Herein, a cyclization reaction by direct use of cyclotron-produced [ 11 C]CO2 is described to obtain various heterocycles intracyclically labeled in only 10 minutes.
