Chiral syntheses of 6′-β-fluoroaristeromycin, 6′-β-fluoro-5′-noraristeromycin and aristeromycin
Carbocyclic nucleosides substituted at the C-6′ position are receiving increasing attention. Chiral synthetic accessibility to the biologically promising 6′-β-fluoroaristeromycin is lacking. Its preparation and that of the 5′-nor analogue are described. A
