Phosphonoacetic acid (PAA, 1) was coupled with various acyclonucleosides, 2'-deoxyuridines, cytidines, and arabinosyluracils, with 2,4,6-triisopropylbenzenesulfonyl chloride (TPS) or dicyclohexylcarbodiimide (DCCI) as condensing agents, to give a range of phosphonate esters. The carboxylic ester linkage of PAA to the 5'-position of 5-bromo-2'-deoxyuridine (BUdR, 3) was achieved via the mixed anhydride

5-(1-methoxy-2-azidoethyl)-2'-deoxyuridines (11). In vitro antiviralactivities against HSV-1-TK(+) (KOS and E-377), HSV-1-TK(-), HSV-2, VZV, HCMV, and DHBV were determined. Of the newly synthesized compounds, 5-(1-cyanamido-2-iodoethyl)-2'-deoxyuridine (6) exhibited the most potent anti-HSV-1 activity, which was equipotent to acyclovir and superior to 5-ethyl-2'-deoxyuridine (EDU). In addition, it was significantly

A novel class of 5-(1-azido-2-haloethyl)arabinouridines 4–6 was synthesized by the regiospecific addition of halogenoazides (XN3: X = C1, Br, I) to the vinyl substituent of 5-vinylarabinouridine (7). The title 5-(1-azido-2-haloethyl)arabinouridines 4–6 were previously shown to exhibit significant in vitro antiviral activity against herpes simplex virus type 1, varicella zoster virus and cytomegalo
