Friedel-Crafts-type acylation of alkenes with acyl chlorides has been successfully conducted with a wide substrate scope by the combined use of AlCl3 and 2,6-dibromopyridine. Trisubstituted alkenes afford allylketones or vinylketones depending on the presence or absence of hydrogen atom(s) at the β-position to the acylation site, while monosubstituted alkenes exclusively afford vinylketones.
Gold(l)-catalyzed cascade cyclization reaction: Highly regio- and diastereoselective intermodular addition of water and alcohols to epoxy alkynes

We have developed a novel access to ketal skeletons through a highly regio- and diastereoselective intermolecular addition of water and alcohols to alkynyl epoxides catalyzed by goid(l). This procedure involves a domino three-membered ring-opening, 6-exo-
Olefination of ketones using a gold(III)-catalyzed Meyer-Schuster rearrangement
Engel, Douglas A.,Dudley, Gregory B.
, p. 4027 - 4029 (2007/10/03)
An atom-economical and efficient olefination strategy for ketones is described. Ethoxyacetylide addition followed by a gold-catalyzed Meyer-Schuster rearrangement affords α,β-unsaturated esters, generally in excellent overall yield from the starting ketones. The alkynophilicity of Au3+ promotes an interaction with the electron-rich acetylenes that catalyzes the Meyer-Schuster rearrangement selectively over other conceivable pathways.
One pot synthesis of α,β-unsaturated ketones from the Mukaiyama aldol condensation
Bouhlel,Hassine
, p. 2183 - 2186 (2007/10/02)
Satisfactory yields of α,β-unsaturated ketones are obtained from two trimethylsilylenol ethers and a variety of aldehydes and ketones in a one pot modified Mukaiyama aldol procedure using triethylamine and trifluoroacetic anhydride.
