A new, practical route to 1-acyl-2-substitutednaphthalenes has been developed by benzoquinone-promoted ZnI 2 -catalyzed benzannulation of 2-alkynylbenzaldehydes with alkenes. This method allows three new bonds, two C=C bonds and one C=O bond, to be constructed in a single reaction.

We report a new efficient gold-catalyzed cyclization of 1,6-diyne-4-en-3-ols to give naphthylketone derivatives under ambient conditions. The value of this cyclization is reflected by its applicability to a wide range of alcohol substrates.
