The first synthesis of 1'-fluoronucleosides, which has long been synthetic targets as the potential antimetabolites, was achieved. Electrophilic fluorination of the 1'-position of a 1'-ketouridine derivative, followed by reduction of the 2'-keto-moiety, gave the protected 1'-fluorouridine derivative and its arabino-type congener. Alternatively, nucleophilic fluorination of a 1'-phenyselenouridine derivative with DAST/NBS produced the protected 1'-fluorouridine and its
-anomer.
