Dichloropyrazinones are reacted with alkenolates or a Grignard reagent in order to tether a dienophilic side-chain at the 3-position. The compounds smoothly undergo intramolecular Diels-Alder reaction forming tricyclic ring systems. The reactions proceed completely stereoselective yielding only endo
