An efficient protocol for the synthesis of γ,δ-unsaturated α-chloroketones has been developed via Au-catalyzed tandem intermolecular hydroalkoxylation/Claisen rearrangement. In the presence of 1 mol% JohnPhosAuCl and 1 mol% NaBArF, a broad range of allylic alcohols smoothly underwent the tandem intermolecular hydroalkoxylation/Claisen rearrangement with aromatic, vinylic or aliphatic chloroalkynes
