 AB    In order to obtain rigidity within the sugar moiety of nucleosides, some
       bicyclic pyrimidine nucleoside analogues were synthesized starting from
       cyclopentanone. The C-3' is fused to C-4' via a propylene linker in
       order to obtain a [3.3.0]-bicyclic ring system wherein the sugar moiety
       should be restricted to mainly the C-1'-exo conformation.
