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

various positions of canonical nucleosides has generated a number of bioactive structural variants. Herein, the synthesis of two unique series of sugar modified nucleosides bearing a gem-dichloro group is presented. The synthetic plan entails the controlled addition of phosphorus pentachloride to suitably protected 2′- or 3′-ketodeoxynucleoside intermediates as the keystep, facilitating the rapid construction

A photochemical method for converting aliphatic alcohols into boronic esters is described. Preactivation of the alcohol as a 2-iodophenyl-thionocarbonate enables a novel Barton-McCombie-type radical deoxygenation that proceeds efficiently with visible light irradiation and without the requirement for a photocatalyst, a radical initiator, or tin or silicon hydrides. The resultant alkyl radical is intercepted
