Review of the Synthesis of 2-Deoxy-5-Tluorouridine Author: Hung-Cheh Chiang, Pei-Len Wang

Abstract：

The synthetic methods of 2'-deoxy-5-fluorouridine (an antitumor drug) reported in-literature were extensively reviewed and discussed.
The most economical synthetic route is the method modifide by Brown(5) 2', 3', 5'-Tri-O-acetyluridine was allowed to react with acetic acid containing fluorine. The reaction mixture was treated with ammonia in methyl alcohol to give 5-fluououridine. which was then deoxygenated to give the 2'-deoxy-5-fluorouridinein the overall yield 71%.
