A one‐step ^18^F‐labelling strategy was used to prepare three labelled analogues of the vitamin biotin, which can be useful as tracers because of biotin's high affinity for avidin. The labelled compounds were obtained in decay‐corrected yields of up to 35% and specific radioactivity of 320 GBq/µmol.
## Abstract The synthesis and preliminary biological evaluation of a lipophilic, fluorine‐18‐labeled 5‐ethynyl‐2′‐deoxyuridine derivative [^18^F]‐**3** is described. Initially, 5‐ethynyl‐2′‐deoxyuridine **5** was synthesized by coupling trimethylsilyl protected acetylene to 5‐iodo‐2′‐deoxyuridine *
