Simple Primary Anilines as Iminium Catalysts for the Epoxidation of α‐Substituted Acroleins

Simple ortho‐alkylated anilines have been shown to be excellent iminium catalysts for the epoxidation reaction of α‐substituted acroleins. A range of different α‐substituted acroleins give the epoxide products in good to excellent yields and good chemoselectivity.
