title: A tandem 1,3-H-shift-6π-electrocyclization-cyclic 2-amido-diene intramolecular Diels-Alder cycloaddition approach to BCD-Ring of atropurpuran.
abstract: An approach toward the BCD-ring of atropurpuran via a sequence of allenic 1,3-H shift, 6π-electron pericyclic ring closure, and intramolecular Diels-Alder cycloaddition of cyclic 2-amidodiene is described.
