Design and synthesis of 3'-deoxy-3'-fluoro-2'-O,3'-C-vinylene-linked bicyclic purine nucleoside.

[摘要]：Starting from D-xylose via a 3-deoxy-3a-C-ethynyl-3-fluoro sugar as a key intermediate, a novel fluorinated bicyclic purine nucleoside has been synthesized. A neighboring-group participation pathway and a mechanism involving an intramol. cycloaddn. induced by fluorine are proposed for the formation of the key intermediate and the bicyclic nucleoside, resp.
