Bs. Ross et al., AN EFFICIENT AND SCALABLE SYNTHESIS OF ARABINOSYLGUANINE AND 2'-DEOXY-2'-FLUORO-GUANOSINE, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1645-1647
An efficient conversion from commercially available 2,6-diaminopurine-
2',3',5'-tri-O-benzyl arabinoside to arabinosylguanine and its further
transformation to 2'-deoxy-2'-fluoro-guanosine is outlined. This proc
ess has been used to produce more than one hundred grams of final prod
uct.
