  Synthesis and biological evaluation of some novel 4′-Thio-l-ribonucleosides with modified nucleobase moieties

  摘要：

  1,2,3,5-Tetra-O-acetyl-4-thio-beta-L-ribofuranose (13) was synthesized by an improved five-step sequence starting from methyl alpha-D-lyxopyranoside. Compound 13 was then converted to the corresponding L-4'-thionucleosides 4-6 and 19 by a modified Vorbruggen procedure. All of these nucleoside analogues were tested for their antitumour activity in vitro. (C) 2003 Elsevier Science Ltd. All rights reserved.
