An efficient electrochemical synthesis of trisubstituted oxazoles from readily available 1,2-diketones and amines is described. With KI as the electrocatalyst, t-BuOK as the base and MeOH as the electrolytic solvent, the electrochemical synthesis could be smoothly performed in an undivided cell to afford 2,4,5-trisubstituted oxazoles in good yields at room temperature.
