Entecavir is a carbocyclic analogue of 2'-deoxyguanosine developed by Bristol-Myers Squibb (USA) in 1997 with potent and selective activity against the hepatitis B virus (HBV). Its structure consists of a five-membered ring and a guanine moiety. Clinically, it demonstrates strong inhibitory effects against the hepatitis B virus and has a relatively low tendency for drug resistance. This review provides a comprehensive summary of reported total and formal syntheses of entecavir to date, covering both early classical strategies and more recent asymmetric approaches featuring high selectivity and efficiency. It emphasizes the key reaction steps in various synthetic pathways. These synthetic efforts not only advance the process development of entecavir but also offer valuable insights for the synthesis of structurally related nucleoside-based antiviral agents.

Key words: entecavir, anti-HBV, total synthesis, asymmetric synthesis
