| Abstract: | The protected analogue of 2-amnio-6-chloropurine arabinoside (3b) was subjected to reaction with diethylaminosulfur trifluoride (DAST) and subsequently treated with NaOAc in Ac2O/AcOH to give N2, O3', O5'-triacetyl-2'-deoxy-2'-fluoroguanosine (5a). After deacetylation of the sugar moiety and protection of 5'-OH by a 4,4'-dimethoxytrityl group, this nucleoside component was converted to 2'-deoxy-2'-fluoroguanyl-(3',5')-guanosine (6c, GfpG). |
