The reaction involves a doublecyclization process through a proposed key gold−cyclopropyl carbeneintermediate that evolves by the intramolecular addition of an aromatic tothe cyclopropane ring, affording polycyclic structures. The enantioselectiveversion was studied using gold(I) complexes bearing chiral ligands.
