✦ Synopsis


A mechanistic investigation into the recently reported intramolecular aryl Diels-Alder reaction was carried out using deuterium labeling. These studies led to the conclusion that the initial Diels-Alder adduct is isomerized to a highly conjugated tetra-ene intermediate which undergoes a stereospecific suprafacial 1,5-dienyl hydrogen shift to give the observed product.

5-Carboxy apoyohimbine ring systems have been prepared via intramolecular Diels-Alder reactions of systems that incorporate electron-deficient dienes and acylamide dienophiles. These mismatched systems cyclise efficiently with exo stereoselectivity.
