title: Synthesis and conformational analysis of pyrimidine nucleoside analogues with a rigid sugar moiety.
abstract: 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.
