Highly substituted benzene derivatives have been easily prepared in a regioselective way from readily available 1,3-hexadien-5-ynes through a gold(I)-catalyzed tandem reaction. The process involves an initial cyclization followed by a selective Wagner–Meerwein shift in which the migration preference seems to be determined by the ability to stabilize a positive charge.
