or both with 1,3-dioxolane in the presence of potassium iodide and chlorotrimethylsilane by a convenient and single-step synthesis. Among the compounds tested, 5-chloro and 5-bromo analogues possessing an acyclic glycosyl moiety were the most effective and selective antiviralagents in the in vitro assays against wild-type duck HBV (EC50=0.4-2.2 and 3.7-18.5 microM, respectively) and human HBV-containing

thio)thymine (HEPT), in which the C-2, N-3, or C-4 position was modified were synthesized. These involve 2-thiothymine (11), 2-thiouracil (12), 4-thiothymine (17), 4-thiouracil (18), 5-methylcytosine (27), and cytosine (28) derivatives. Preparation of N-3-substituted derivatives (29 and 30) of HEPT was also carried out. Among these analogues, compound 11 exhibited excellent activity against HIV-1 HTLV-IIIB
