Two novel classes of bicarbocyclic dideoxynucleosides have been synthesized for antiviral studies. The key intermediates, 9 and 23, synthesized in multiple steps from readily available monocyclic or bicyclic precursors, were coupled with the desired heterocyclic bases to afford, after further elaboration, the corresponding bicarbocyclic dideoxynucleosides. The structure and stereochemistry of the tosylate intermediates and the target bicarbocyclic dideoxynucleosides were confirmed by extensive H-1 and C-13 NMR studies including COSY, NOESY, DEFT, and selective INEPT experiments.

The synthesis of some carbaprostacyclin precursors
8-diene-3/gb-ol, which has previously been resolved, a series of transformations are described which provide access to a variety of chiral intermediates for the synthesis of carbaprostacyclin and prostaglandin derivatives. Amongst these precursors are 8-acetoxybicyclo[3.3.0]oct-2-ene, 8-acetoxybicyclo[3.3.0]octane-2-carboxaldehyde and a deoxyCorey lactone derivative.
