Access to fused pyrroles via the reaction of spiro-dienyl ethers with amines involving a chemoselective skeletal rearrangement

Abstract Under metal-free conditions, the reaction of spiro-dienyl ethers, derived from furan derivatives, with aromatic amines provided fused pyrroles. The reaction proceeded through an interesting and chemoselective skeletal rearrangement and provided an alternative protocol for the construction of pyrrole rings from furan derivatives.
