Abstract
B3LYP/6-31+G(d) calculations of structures and relative energies for compet ing transition states for intramolecular Diels-Alder reactions of substitut ed 3,5-hexadienyl acrylates and acrylamides show that boatlike conformation s are sometimes favored in the forming ring that includes the tether.
