Abstract

Throw your hat in the ring: A highly diastereoselective synthesis of the ABC rings of (−)‐norzoanthamine has been achieved starting from the (−)‐Hajos–Parrish ketone (see scheme). Three asymmetric quaternary carbon centers on the C ring were constructed by a 1,4‐addition, and an intramolecular Diels–Alder reaction provided a trans‐decalin scaffold on the AB rings.magnified image
