Gold(I)-catalyzed 6-endo hydroxycyclization of 7-substituted-1,6-enynes Sanjuán Cortázar, Ana María Martínez Cuezva, Alberto García García, Patricia Fernández Rodríguez, Manuel A. Sanz Díez, Roberto catalysis dihydronaphthalenes gold gold catalysis hydroxycyclization selectivity Química orgánica Chemistry, Organic The cyclization of o-(alkynyl)-3-(methylbut-2-enyl)benzenes, 1,6-enynes having a condensed aromatic ring at C3–C4 positions, has been studied under the catalysis of cationic gold(I) complexes. 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 Ministerio de Ciencia e Innovación (MICINN) and FEDER (CTQ2010-15358) 2015-07-27T11:30:48Z 2015-07-27T11:30:48Z 2013-10 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1860-5397 http://hdl.handle.net/10259/3800 10.3762/Fbjoc.9.263 eng Beilstein Journal of Organic Chemistry, 2013.
