Beschreibungen/Notizen

• 3′,5′-Di-O-protected 6-chloropurine arabinoside 4b was treated with diethylaminosulfur trifluoride (DAST) and subsequently deprotected with pyridinium p-toluenesulfonate to give 6-chloropurine 2′-deoxy-2′-fluororiboside 6a. The displacement with nucleophile afforded the 6-substituted congener 6b-e. Treatment of 5′-O-protected 6-chloropurine arabinoside 3c with DAST gave lyxoepoxide 7.
