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

抄録

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.
