An Efficient Route to Benzene and Phenol Derivatives via Ring-Closing Olefin Metathesis

Abstract

Without the formation of inseparable regioisomers, ­various substituted phenol derivatives 2 and benzene derivatives 4 were prepared through RCM-tautomerization and RCM-dehydration protocols. A new synthetic route to precursors 1 and 3 enabled efficient access to these aromatic compounds.
