We report the synthesis of acyclic and spiranic imidazole-derived C-selenonucleosides. 5-Hydroxy-4-tetrahydroxybutyl imidazolidine-2-selones, a novel class of acyclic selenonucleosides, were transformed into (tetrahydroxybutylimidazol-2-yl)diselenide, by acetylation and chemoselective N-deacetylation with methanolic imidazole. Furthermore, the synthesis of a new class of conformationally restricted
