  Synthesis of L-3'-azido-3'-deoxythymidine (L-AZT) and its stereoisomers

  摘要：

  We report the first synthesis of the L isomer of 3'-azido-3'-deoxythymidine (L-AZT). L-Arabinose was used as starting material for preparation of appropriately protected alpha,beta-unsaturated aldehyde 5. Michael-type addition of azide to 5 gave 3-azido-2,3-dideoxypentofuranoses 7 and 8 suitable for nucleoside coupling with silylated thymine to afford after deprotection L-AZT (11), 1-(3-azido,-2,3-dideoxy-alpha-L-erythro-pentofuranosyl)thymine (12), 1-(3-azido-2,3-dideoxy-beta-L-threo-pentofuranosyl)thymine (13) and 1-(3-azido-2,3-dideoxy-alpha-L-threo-pento-furanosyl)thymine (14). Anti-HIV activity of L-AZT is discussed.
