Alumina-Mediated π-Activation of Alkynes

The ability to induce powerful atom-economic transformation of alkynes is the key feature of carbophilic π-Lewis acids such as gold- and platinum-based catalysts. The unique catalytic activity of these compounds in electrophilic activations of alkynes is explained through relativistic effects, enabling efficient orbital overlapping with π-systems. For this reason, it is believed that noble metals are indispensable components in the catalysis of such reactions. In this study, we report that thermally activated γ-Al2O3activates enynes, diynes, and arene-ynes in a manner enabling reactions that were typically assigned to the softest π-Lewis acids, while some were known to be triggered exclusively by gold catalysts. We demonstrate the scope of these transformations and suggest a qualitative explanation of this phenomenon based on the Dewar-Chatt-Duncanson model confirmed by density functional theory calculations.

A gold(i)-catalyzed intramolecular tandem cyclization reaction of alkylidenecyclopropane-containing alkynes

A novel gold(i)-catalyzed intramolecular tandem cyclization reaction of ortho-(arylethynyl)arenemethylenecyclopropanes provided an efficient approach to prepare functionalized 11H-benzo[a]fluorene derivatives in moderate to good yields. Further transformations as well as applications of the products have been presented and a plausible reaction mechanism has also been proposed on the basis of deuterium labeling and control experiments.

Gold-catalyzed oxidative cyclizations of 2-oxiranyl-1-alkynylbenzenes for diastereoselective synthesis of highly substituted 2-hydroxyindanones

We report the gold-catalyzed oxidative cyclizations of 2-oxiranyl-1- alkynylbenzenes into highly substituted 2-hydroxyindanone frameworks bearing a tertiary alcohol. Such gold-catalyzed reactions comprise an initial internal redox reaction, sulfoxide oxidation of α-carbonyl gold-carbenoids, followed by gold-catalyzed formal ene reactions on the resulting diketone intermediates.
