title: Stereoselective synthesis of 1'-C-carbon-subsituted 4'-thionucleosides from 4-thiofuranoid glycal.
abstract: PhSeCl or NIS-initiated glycosylation to 2-5, which were prepared through lithiation of 4-thiofuranoid glycal 1, proceeded stereoselectively to give the target 1'-C-carbon-substituted 4'-thiopyrimidine nucleosides. This synthetic method enabled us to synthesize 4'-thioanalogue 13 of nucleoside antibiotic angustmycin.
