[Structure: see text] An efficient route to L-beta-3'-deoxy-3',3'-difluoro-4'-thionucleosides, thio-containing analogues of highly bioactive gemcitabine, is described. Our synthesis highlighted the installation of the thioacetyl group in high efficiency and construction of 3-deoxy-3,3-difluorothiofuranose skeleton in a novel method.
