(+)-Cyclaradine, carbocyclic arabinofuranosyladenine having anti-HSV activity, has been synthesized from (-)-2-azabicyclo[2.2.1]hept-5-en-3-one in only seven steps. The method involves the novel ring cleavage of epoxide by neighboring participation.
Biocatalytical Transformations- VI. The 4-Acetamido-cyclopent-2-ene Carboxylate Route Revisited: Synthesis of (+)- and (-)-Aristeromycin

Enantiomerically pure (+)-as well as (-)-aristeromycin can be synthesized starting from (+)- or (-)-butyl (or hexyl) 4-acetamido-cyclopent-2-ene carboxylate; these carboxylates are easily obtained from their corresponding racemates by hydrolysis with the lipase from Candida rugosa.
Carbocyclic analogues of xylofuranosylpurine nucleosides. Synthesis and antitumor activity
Vince,Brownell,Daluge
, p. 1358 - 1360 (2007/10/02)
(±)-4α-Amino-2α,3β-dihydroxy-1α-cyclopentanemethanol (6), the carbocyclic analogue of xylofuranosylamine, was synthesized from the previously reported 4α-acetamido-2α,3α-epoxycyclopentane-1α-methanol. Amine 6 was converted to (±)-4α-[(5-amino-6-chloro-4-pyrimidinyl)amino]-2α,3β-dihydroxy-1α-cyc lopentanemethanol (7) by condensation with 5-amino-4,6-dichloropyrimidine. From 7, the carbocyclic analogues of xylofuranosyladenine and xylofuranosyl-8-azaadenine were prepared. In contrast to 9-β-D-xylofuranosyladenine and its 8-aza analogue, the corresponding carbocyclic nucleosides were resistant to deamination by adenosine deaminase. The carbocyclic 8-aza derivative exhibited significant in vivo antitumor activity which varied according to treatment schedule.
Carbocyclic Sugar Amines: Synthesis and Stereochemistry of Racemic α- and β-Carbocyclic Ribofuranosylamine, Carbocyclic Lyxofuranosylamine, and Related Compounds

The facile and stereoselective synthesis of racemic carbocyclic β-ribofuranosylamine, carbocyclic β-lyxofuranosylamine, and related 2,3-cis-dihydroxy carbocyclic pentofuranosylamines is reported.In addition, the synthesis, isolation, and base-catalyzed epimerization of methyl cis-4-aminocyclopent-2-enecarboxylate are described.The epimerization at C(1) followed by stereoselective cis hydroxylation provides for the first time access to the racemic carbocyclic α-pentofuranosylamines.
