One-Pot Synthesis of Phenol Derivatives by the Novel Intramolecular Alder–Rickert Reaction: Effects of Aryl Substituent at the 3-Position of Cyclohexenone Derivatives on Reactivity
We examined In(OTf)3-catalyzed enolization and intramolecular Alder-Rickert reactions of cyclohexenone derivatives. The 3-aryl substituted cyclohexenone derivatives bearing an ethoxycarbonyl-substituted alkyne moiety could be converted into the corresponding phenols in comparatively good yield.

A novel carbocyclic thermal rearrangement of 4-substituted 2-cyclohexen-1-ones is suggested to involve a 'masked' ene reaction and provides a facile route to spirocyclic cyclohexenone systems.
