Abstract

Practical methods for the synthesis of three stereoisomers of Entecavir have been developed. Starting from the reported intermediate (1S,2R)-2-((benzyloxy)methyl)cyclopent-3-en-1-ol and (1R,2S)-2-((benzyloxy)methyl)cyclopent-3-en-1-ol, respectively, three stereoisomers of Entecavir have been prepared with 17–20% overall yields. In principle, other stereoisomers could also be prepared by using the materials and reactions described in this article.

Key words

Entecavir - synthesis - stereoisomers - stereoselective - hepatitis B
