Both enantiomers of a functionalized bicyclo[3.2.1]octane molecule potentially useful as a versatile chiral building block have been prepared in enantiomerically pure forms from norbomadiene by employing lipase-mediated kinetic resolution. By transforming both enantiomers enantioconvergently into the same chiral lactone serving as the key intermediate for the synthesis of the naturally occurring carbocyclic nucleoside (-)-aristeromycin, the absolute configuration of the resolved products has been established and at the same time their synthetic potential has been demonstrated.

Asymmetric synthesis of -2,3-dihydroxy-4-hydroxymethylcyclopent-1ylmalonate (its racemic form is already known as a versatile building block for carbocyclic C-nucleosides) was achieved by Diels-Alder reaction of cyclopentadiene with di-l-ment
