which was then converted to the ureaderivative 5 and cyclopropylamine 7 by Curtiusrearrangement of an acyl azide. The urea intermediate 5 was utilized to prepare thymine 10, uracil 11, and cytosine 14 derivatives. The hypoxanthine, adenine, and guanine nucleosides 21, 22, and 24 were synthesized from the amino intermediate 7.

As further representatives of a novel class of carbocyclic nucleosideanalogues (±)-cis- and (±)-trans-(2-hydroxymethylcyclopropyl)-uracil, -thymine, and -inosine were synthesized from the corresponding dialkyl 1,2-cyclopropane dicarboxylates.
