<description>A gold(I)-catalyzed cascade reaction for the stereoselective&#xd;
synthesis of sulfur- or selenium-containing indeno[1,2-b]chromene&#xd;
derivatives from o-(alkynyl)styrenes substituted at the triple bond with a&#xd;
thio- or seleno-aryl group is described. The reaction involves a double&#xd;
cyclization process through a proposed key gold−cyclopropyl carbene&#xd;
intermediate that evolves by the intramolecular addition of an aromatic to&#xd;
the cyclopropane ring, affording polycyclic structures. The enantioselective&#xd;
version was studied using gold(I) complexes bearing chiral ligands.</description>
