2015-07-27T09:55:12Z urn:hdl:10259/3799 Solvent- and ligand-induced switch of selectivity in gold(I)-catalyzed tandem reactions of 3-propargylindoles Álvarez Manuel, Estela Miguel, Delia García García, Patricia Fernández Rodríguez, Manuel A. Rodríguez, Félix Sanz Díez, Roberto catalysis gold indoles Nazarov cyclizations selectivity The selectivity of our previously described gold-catalyzed tandem reaction, 1,2-indole migration followed by aura-iso-Nazarov cyclization, of 3-propargylindoles bearing (hetero)aromatic substituents at both the propargylic and terminal positions, was reversed by the proper choice of the catalyst and the reaction conditions. Thus, 3-(inden-2-yl)indoles, derived from an aura-Nazarov cyclization (instead of an aura-iso-Nazarov cyclization), were obtained in moderate to good yields from a variety of 3-propargylindoles 2015-07-27T09:55:12Z 2015-07-27T09:55:12Z 2011-06 info:eu-repo/semantics/article 1860-5397 http://hdl.handle.net/10259/3799 10.3762/bjoc.7.89 eng Beilstein Journal of Organic Chemistry. 2011, v. 7, p. 786–793 Gold catalysis for organic synthesis http://dx.doi.org/10.3762/bjoc.7.89 info:eu-repo/grantAgreement/MICINN/CTQ2010-15358 info:eu-repo/grantAgreement/MICINN/CTQ2009-09949 info:eu-repo/grantAgreement/JCyL/BU021A09 info:eu-repo/grantAgreement/JCyL/GR-172 http://creativecommons.org/licenses/by/4.0/ Este documento está sujeto a una licencia de uso Creative Commons, por la cual está permitido hacer copia, distribuir, comunicar públicamente, remezclar, transformar y crear a partir del material para cualquier finalidad, incluso comercial, siempre que se cite al autor original, se proporcione un enlace a la licencia y se indique si se han realizado cambios info:eu-repo/semantics/openAccess Attribution 4.0 International Beilstein-Institut
