Abstract
Attempted fluorination of ro-pentofuranosyl)-3-(2-methoxyethoxymethyl) uracil (12) and -erythro-pentofuranosyl)-3-(2-methoxyethoxymethyl) ura cil (14) with diethylaminosulfur trifluoride (DAST) produced very reac tive N-3-MEM-O-2,2- and N-3-MEM-O-2,3-anhydronucleoside intermediates (16) that reacted with KF to give the desired fluorinated nucleosides with retention of configuration.
