The selective 6-endo-dig mode of cyclization observed for the 7-substituted substrates in the presence of water or methanol giving rise to hydroxy(methoxy)-functionalized dihydronaphthalene derivatives is highly remarkable in the context of the observed reaction pathways for the cycloisomerizations of 1,6-enynes bearing a trisubstituted olefin eng 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 catalysis dihydronaphthalenes gold gold catalysis hydroxycyclization selectivity Gold(I)-catalyzed 6-endo hydroxycyclization of 7-substituted-1,6-enynes info:eu-repo/semantics/article
