| Outline of Final Research Achievements |
Luminamicin was found to exhibit selective antibacterial activity against anaerobic bacteria by our group in 1985. It contains a highly functionalized 11-oxatricycloundecane, associated with a 10-membered lactone moiety which possesses a (E)-trisubstituted olefin and a 14-membered macrolactone, with an enol ether conjugated with a maleic anhydride functionality. Due to its intriguing structure and interesting biological activity, we have been focusing on its total synthesis.
Herein, we report the construction of core frameworks; 1) the oxa-bridged cis-decalin ring system bearing a side chain utilizing Michael-aldol reaction and 1,6-oxa-Michael reaction, and 2) the 10-membered lactone using a ring expansion reaction of an acetal through intramolecular Julia coupling.
