condensation of the cyclopentenyl α,-tosylate with the alkali metal salts of 6-chloropurine and uracil, afforded the protected carbocyclic nucleosides and , respectively, which were converted to neplanocin a () and cyclopentenyl uracil () by established methods.

(−)-Neplanocin C (4), a minor component of the neplanocin family of antibiotics and a lead drug for the design of several conformationally constrained nucleosides analogues, was enantioselectively synthesized starting from d-ribono-1,4-lactone via a convergent approach in twelve steps. The proton NMR spectrum of 4 was in agreement with the corresponding natural product. Calculated coupling constants
