A new divergent asymmetric synthesis of (+)- and (-)-ethosuximides and their anticonvulsant activities

Both enantiomers of ethosuximide were synthesized divergently from nitroolefin lactone [(-)-2a] or [(-)-2b], which was obtained by asymmetric nitroolefination of α-methyl-γ-butyrolactone with chiral nitro enamines derived from L-proline. Although anticonv
