                                    Enantioselective synthesis of pyrimidine and purine cyclopropyl carbocyclic L-nucleosides has been accomplished from L-gulono-gamma-lactone and the X-ray structure of the key intermediate 9,(1R,2S,4'R)-2-(2,2-dimethyl-1,3-dioxolan-4-yl)cyclopropyl urea, has been determined.
