When cascadecyclizations initiated by Lewis acid-mediated opening of an epoxide are terminated through reaction with a MOM-protected phenol, a tandem electrophilic aromatic substitution can be obtained. This highly regioselective tandem process has been employed in the first synthesis of (+)-angelichalcone.
