The enantiomeric synthesis of β-D-cyclopropyl carbocyclic nucleosides was achieved via the key intermediate 5. Thymine and uracil derivatives 7 and 9 were obtained by oxidation, Curtius rearrangement and the standard construction method of pyrimidines. The cytosine derivative 10 was prepared from 9via the 4-triazole intermediate.
