Enamide-benzyne-[2 + 2] cycloaddition: stereoselective tandem [2 + 2]-pericyclic ring-opening-intramolecular N-tethered [4 + 2] cycloadditions.

ABSTRACT: Benzyne-[2 + 2] cycloadditions with enamides are described. This effort led to the development of a highly stereoselective tandem [2 + 2] cycloaddition-pericyclic ring-opening-intramolecular-N-tethered-[4 + 2] cycloaddition for rapid assembly of nitrogen heterocycles.
