Nucléosides de synthése XXII: Obtention,comme synthons oligoxylonucléotidiques,de d-xylofurannosyl adenines spécifiquement substitués

This work describes the synthesis of certain nucleoside synthons which are necessary in order to obtain oligoxylonucleotides. The utilization of a non-symmetrically substituted xyloside substituted at the 2-position permits one to obtain, in satisfactory yields, the described nucleoside which is conveniently protected. All of the compounds described have been fully characterized using the usual analytical methods.
