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 1860-5397 http://hdl.handle.net/10259/3800 10.3762/Fbjoc.9.263 catalysis dihydronaphthalenes gold gold catalysis hydroxycyclization selectivity Gold(I)-catalyzed 6-endo hydroxycyclization of 7-substituted-1,6-enynes
