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 MICINN (CTQ2010-15358 and CTQ2009-09949), Junta de Castilla y Leon (BU021A09 and GR-172), MEC (FPU predoctoral fellowship to D.M.), Ramón y Cajal (contract to M.A F R.), Juan de la Cierva (contract to P.G.G.) application/pdf eng Beilstein-Institut 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 Attribution 4.0 International 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 catalysis gold indoles Nazarov cyclizations selectivity Química orgánica Chemistry, Organic Solvent- and ligand-induced switch of selectivity in gold(I)-catalyzed tandem reactions of 3-propargylindoles info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
