Virumbrales Ortiz, Cintia Mahmoud Abd El Aleem Ali, Elremaily Suarez Pantiga, Samuel Fernández Rodríguez, Manuel A. Rodríguez, Félix Sanz Díez, Roberto 2022-10 A gold(I)-catalyzed cascade reaction for the stereoselective synthesis of sulfur- or selenium-containing indeno[1,2-b]chromene derivatives from o-(alkynyl)styrenes substituted at the triple bond with a thio- or seleno-aryl group is described. The reaction involves a double cyclization process through a proposed key gold−cyclopropyl carbene intermediate that evolves by the intramolecular addition of an aromatic to the cyclopropane ring, affording polycyclic structures. The enantioselective version was studied using gold(I) complexes bearing chiral ligands. application/pdf http://hdl.handle.net/10259/7405 eng American Chemical Society Gold(I) Catalysis Applied to the Stereoselective Synthesis of Indeno[2,1-b]thiochromene Derivatives and Seleno Analogues info:eu-repo/semantics/article TEXT RIUBU.
