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 CC-LICENSE license_rdf license_rdf application/rdf+xml; charset=utf-8 908 https://riubu.ubu.es/bitstream/10259/3799/8/license_rdf 0175ea4a2d4caec4bbcc37e300941108 MD5 8 THUMBNAIL Beilstein_J._Org._Chem._2011.pdf.jpg Beilstein_J._Org._Chem._2011.pdf.jpg IM Thumbnail image/jpeg 4537 https://riubu.ubu.es/bitstream/10259/3799/7/Beilstein_J._Org._Chem._2011.pdf.jpg 1995149493d0c23397e853f0bb97b6f6 MD5 7 ORIGINAL Beilstein_J._Org._Chem._2011.pdf Beilstein_J._Org._Chem._2011.pdf application/pdf 478729 https://riubu.ubu.es/bitstream/10259/3799/1/Beilstein_J._Org._Chem._2011.pdf 4794567bb133feb28ac63529015c6909 MD5 1 LICENSE license.txt license.txt text/plain; charset=utf-8 1362 https://riubu.ubu.es/bitstream/10259/3799/5/license.txt 5d013bfa6e473ff0db22cd82a4d71a70 MD5 5 TEXT Beilstein_J._Org._Chem._2011.pdf.txt Beilstein_J._Org._Chem._2011.pdf.txt Extracted text text/plain 24340 https://riubu.ubu.es/bitstream/10259/3799/6/Beilstein_J._Org._Chem._2011.pdf.txt e4ac36979c387e55e5932415537ec35b MD5 6 10259/3799 oai:riubu.ubu.es:10259/3799 2021-11-10 10:38:24.367 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
