The stereoselectivity of the intramolecular Diels-Alderreactions of terminally activated trienes and increases as the dienophile activating group is changed along the series CONR2 < CO2Me < COMe < CHO. Further increases in selectivity are realized by using Lewis acid catalysts. These results are consistent with predictions based on the nonsynchronous transition state hypothesis.
