Abstract 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 ...
