Abstract

A key compound, 2-amino-6-chlor-9-(2,3-dideoxy-3-fluoro-beta-D-erythro-pentofuranosyl)puine, was prepared from 2-amino-6-chloropurine riboside in 5 steps, then subjected to the nucleophilic displacement with benzenethiols to afford 6-arylthio congeners. These compounds showed a similar anti-HBV effect to that of 2',3' dideoxy-3'-fluoroguanosine.
