Abstract
Five novel(2S,4S)-5-alkyl-2-thia-5-azabicyclo[2.2.1]heptan-3-one derivatives were synthesized from trans-4-hydroxy-L-proline by N-alkylation reaction,esterification reaction,sulfonylation reaction,potassium thioacetate reaction and configuration inversion,hydrolysis of ester group,condensation and salt formation.The structures were characterized by 1 H NMR and MS.
