A new Synthetic Approach to Quassinoids via an Intramolecular Diels-Alder Reaction: A Stereoselective Construction of the Klaineanone Ring System

Thermolysis of the benzocyclobutene derivative (25) prepared from norcamphor (6) gave stereoselectively the tetracyclic compound (27), which was converted into the D-deoxyquassinoid derivative (2) possessing the same ABCD-ring fusion as that of klaineanon
