Abstract

The chiral total synthesis of paniculide A (1), a highly oxygenated sesquiterpene possessing a bisabolane skeleton, starting from D-glucose is described. The two different approaches, both involved Ferrier's carbocyclization reaction to construct the cyclohexane unit in 1, were explored. The first approach, employing the carbocyclization of bicyclic substrate furnished the formal total synthesis. The second approach, designed to suppress the undesired side reactions observed in the first one, adopted the carbocyclization of a monocyclic substrate, and Claisen rearrangement for the stereoselective carbon-carbon bond formation. The successful total synthesis of I revealed the effectiveness of the combination of Ferrier's carbocyclization and Claisen rearrangement for the chiral synthesis of highly oxygenated natural products possessing cyclohexane units.
