A series of 2'-deoxy-4'-thionucleosides are synthesized by coupling 1-O-acetyl-2-deoxy-3,5-di-O-benzyl-4-thio-D-erythro-pentufuranose to trimethylsilylated nucleobases using natural phosphate doped with trifluoromethanesulfonic acid as catalyst. The detail of this one-pot method and the comparison between the percentage of and -2'-deoxy-4'-thionucleosides with those described previously are also reported.
