摘要: A desymmetrization approach for the synthesis of the A-B-C tricycle intermediate of iso-merrilactone A was described. The key steps of this synthesis to efficiently access the tetracyclic Illicium sesquiterpenes core included an intramolecular aldol cyclization and an oxidative lactonization reaction. A novel Au catalyzed hydrolytic cyclorearrangement cascade reaction was explored in the initial stage.
