title: The First Organocatalytic Cope Rearrangement.
abstract: Exploiting the concept of iminium ion catalysis led to the discovery of the first organocatalytic Cope rearrangement of 1,5-hexadiene-2-carboxaldehydes. A diazepane catalyst exhibited optimal catalytic efficiency and offers possibilities for chiral modification.
