Construction of the [5-7-6] tricyclic core of guanacastepenes was attempted by using the intramolecularDiels-Alder (IMDA) reaction and Me(3)Al-mediated ring opening of the oxabridge as key synthetic steps. The illustrated chemistry demonstrated a synthetic feasibility to build up the framework of guanacastepenes by the IMDA reaction. [reaction: see text]
