Fifteen novel six-membered azanucleoside derivatives were prepared and evaluated for their anti-hepatitisBvirus (HBV) activity and cytotoxicity in human hepatoblastoma-derived liver Hep-G2 cells. The most potent compound 16b with an IC50 value of 2.74 μg/mL (lower than 3TC) and a SI value of 13.5 was disclosed. The key synthetic steps involved the rearrangement of lactones (which were readily obtained
