CONVENIENT SYNTHESIS OF FLUORINATED NUCLEOSIDES WITH PERFLUOROALKANESULFONYL FLUORIDES
摘要:
Perfluoroalkanesulfonyl fluorides are effective dehydroxy-fluorination agents for the hydroxyl group at the sugar moiety of nucleoside derivatives and give the corresponding fluorinated nucleosides in good yield with an inversion of configuration in a single step.

small-molecule inhibitors of the enzyme deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase) from parasitic protozoa. The successful synthesis of a variety of analogues of dUMP is described in which the substituents are introduced at the 3'- and 5'-positions, together with variation in the heteroatom at the 5'-position. The compounds were assayed against recombinant Plasmodiumfalciparum and Leishmania
