Outline of Final Research Achievements

We have developed an efficient regioselective formation of six-/seven-membered cyclic ethers based on gold-catalyzed intramolecular hydroalkoxylation. We demonstrated sequential cyclization/cross-coupling reactions to afford polycyclic ethers. Furthermore, stereoselective synthesis of the ent-ZA′B′C′D′-ring system of maitotoxin has been accomplished through a convergent strategy utilizing Suzuki-Miyaura cross coupling reaction.
