Straightforward Synthesis of 1-(2,3-Dideoxy-β-D-Glycero-Pent-2-Enofuranosyl)-Thymine

Abstract
A two steps synthesis of the antiviral drug (d4T) 3 from thymidine 1 is proposed, which implies a concomitant deprotection-elimination process by action of t-BuOK in DMF on 5′-O-t-butyldimethylsylil-3′-O-methanesulfonyl-thymidine 2.
