2′-Fluoro-3-deazaaristeromycin

The carbocyclic nucleoside 3-deazaaristeromycin has shown biological promise but a library of its derivatives upon which to expand this property is lacking. To address this situation, the synthesis of the two diastereomers of 2′-fluoro-3-deazaaristeromycin is described in a multistep convergent process that calls upon d-ribose for construction of the cyclopentyl fluoro units.
