A lipase-mediated route to (+)-juvabione and (+)-epijuvabione from racemic norcamphor

Nagata, Hiroshi,Taniguchi, Takahiko,Kawamura, Mitsuhiro,Ogasawara, Kunio

, p. 4207 - 4210 (2007/10/03)

(+)-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.
