An enantioselective synthesis of functionalized cyclopentanes has been used to access carbocyclic nucleoside analogs. This pathway allows access to carbocyclic C- or carbocyclic N-nucleosides from a common intermediate, ester 16. Additionally, (1R,2R,3S,4R)-4-amino-2,3-dihydroxy-1-cyclopentanemethanol (18), an intermediate in the total synthesis of aristeromycin, has been prepared as a single enantiomer in eight isolated steps from cyclopentadiene. Progress toward the synthesis of novel carbocyclic C-nucleosides is also discussed.
