Abstract

(+)-Juvabione and (+)-epijuvabione, natural sesquiterpenes exhibiting insect juvenile hormone activity, have been synthesized from (±)-norcamphor via the both enantiomeric intermediates having bicyclo [3.2. 1] octane framework by employing a lipase-mediated kinetic ester-hydrolysis reaction and cyclopropane ring-expansion reaction as the key steps.
