[GRAPHICS]The new cyclopropyl carbocyclic nucleosides 1 and 2 have been synthesized by following short and efficient routes starting from conveniently protected (-)-(Z)-methanohomoserine derivative 3. Both products 1 and 2 bear a quaternary stereogenic center and have opposite chirality, Moreover, the adenine derivative 2 belongs to a new class of cyclopropyl nucleoside showing an amino alcohol function at C-1 in addition to a methylene spacer between the base and the carbocyclic ring.
