A new method for the generation of indole-2,3-quinodimethanes and 2-(N-alkoxycarbonylamino)-1,3-dienes. Intramolecular Heck/Diels-Alder cycloaddition cascade starting from acyclic alpha-phosphoryloxy [corrected] enecarbamates.
An intramolecular Heck/Diels-Alder cycloaddition cascade starting from acyclic alpha-phosphono enecarbamates has been developed to prepare nitrogen heterocycles via indole-2,3-quinodimethanes and 2-(N-alkoxycarbonylamino)-1,3-dienes.
