A highly efficient asymmetricsynthesis of (1S,2R)-2-aminocyclooctanecarboxylic acid has been completed. This asymmetricsynthesis using cycloocta-1,5-diene as the starting material is achieved in 77% yield via a four-step sequence from tert-butyl cycloocta-1,7-dienecarboxylate 10 where the extra double bond adjacent to the unsaturated ester is essential to improve the yield. Furthermore, the Michael
