## Abstract Several 2′‐deoxy‐2′‐[^18^F]fluoro‐1‐__β__‐D‐arabinofuranosyluracil derivatives have been synthesized. Coupling of 1‐bromo‐2‐deoxy‐2‐[^18^F]fluoro‐3,5‐di‐O‐benzoyl‐__α__‐D‐arabinofuranose **2** with protected uracil derivatives **3a–e** followed by hydrolysis and high‐performance liquid
## Abstract Direct fluorination of a pyrimidine nucleoside at the 2′‐arabino‐position has been deemed to be extremely difficult, if not impossible. The conventional synthesis of 2′‐deoxy‐2′‐fluoro‐5‐methy‐1‐β‐D‐arabinofuranosyluracil (FMAU) and its 5‐substituted analogs involves stereospecific fluo
