Abstract
An-T-biotic: The first total synthesis of the T-shaped bisanthraquinone natural product BE-43472B was accomplished and its absolute configuration assigned. Key transformations in the pivotal cascade sequence include a Diels-Alder reaction, a hemiketal formation, and a nucleophilic aromatic ipso substitution.
