title: Synthesis study of 3'-alpha-fluoro-2',3'-dideoxyguanosine.
abstract: A synthetic method was established for 3'-alpha-fluoro-2','3-dideoxyguanosine 1 from guanosine 2 in 27% overall yield and 6 steps. A byproduct 6a of fluorination was identified by NMR studies, its presence strongly supporting our supposition that the fluorination itself proceeded via a bromonium cation.
