title: Synthesis of 2'-deoxy and 2',3'-dideoxynucleoside derivatives from thioglycosides.
abstract: The synthesis of both 2'-deoxy and 2',3'-dideoxynucleoside derivatives by the reaction of thioglycosides with nucleoside bases was examined. The stereochemical outcome at the anomeric position was found to depend on the protecting groups and the C-3 configuration in the sugar moiety, the kind of activator, and the reaction temperature. Based on these findings, 2'-deoxy-D-xylo nucleoside and 2',3'-dideoxynucleoside derivatives have been synthesized in beta-selective manner.
