The reactivity of 7‐alkynycycloheptatrienes tethered to an aryl group under π‐acid catalysis has been studied. A variety of useful cyclic products were synthesized via Au(I)‐catalyzed skeletal reorganization, Cu(II)‐catalyzed hydroarylation, or Brønsted acid‐catalyzed tandem hydroarylation/Friedel‐Craftsreaction. We also report a rare type of skeletal reorganization involving the 1,3‐acetonide tether

An efficient and environmentally benign method was developed to synthesize the benzocycles from phenyl substituted allylic acetates through gold catalyzed Friedel-Crafts type carbocyclization reaction. Different substitution patterns were investigated, which gave a series of benzocyclohexane derivatives in moderate to excellent yields. (C) 2011 Elsevier Ltd. All rights reserved.
