aminocyclopent-3-enecarboxylates, which were derived from a racemic bicyclic β-lactam. The synthetic strategy involves the stereoselective dihydroxylaton of the C–C doublebond of the cyclopentene β-amino esters. The subsequent NaIO4-mediated ring cleavage affords dialdehyde intermediates that undergo functionalization by a Wittig reaction.

Isoxazoline-fused 2-aminocyclopentanecarboxylate derivatives were regio- and stereo-selectively synthesized by nitrile oxide1,3-dipolarcycloaddition to cis- or trans-ethyl-2-aminocyclopent-3-enecarboxylates. The compounds were prepared in enantiomerically pure form by enzymatic resolution of the racemic bicyclic β-lactam.

This invention provides highly regioselective and stereoselective processes for preparing synthetic nucleosides. A process for the preparation of synthetic nucleosides is provided that comprises a) preparing a bicycloamide derivative, b) reacting the bicycloamide derivative with a nucleic acid base or heterocyclic base or salt thereof in the presence of a transition metal catalyst to form a cyclopentenecarboxamide, and c) cleaving a carboxamide group from the cyclopentenecarboxamide to form the synthetic nucleoside. The processes according to the invention can be used for the synthesis of a variety of anti-viral agents, including Abacavir, Carbovir, and Entecavir, as well as derivatives thereof.

A facile selective method has been developed for the synthesis of new fluorine-containing cispentacin stereoisomers. Mono- and difluorinated cispentacin derivatives were synthetized from a bicyclic β-lactam in five or six steps involving a regio- and stereoselective hydroxylation through iodooxazoline formation, followed by deoxygenation by fluorination. Starting from an enantiomerically pure bicyclic
