An Approach to Quassimarin Based on an Exo-Selective Intramolecular Diels-Alder Reaction

A novel exo-selective intramolecular Diels-Adler reaction is used to secure the preparation of the tricyclic adduct 2, a material that contains three of the rings and five of the stereogenic centers present in the bitter principal quassimarin.
