In oxidative electrochemical organic synthesis, radical intermediates are often oxidized to cations on the way to final product formation. Herein, we describe an approach to transform electrochemically generated organic radical intermediates into neutral products by reaction with a metalcatalyst. This approach combines electrochemical oxidation with Cu catalysis to effect formal aza‐Wacker cyclization

4,5-Disubstituted 2-imino-1,3-dioxalanes readily add to oxiranes in the presence of AlCl3, furnishing 1,3-oxazolidin-2-ones in a stereospecific manner, where the configurations of oxiranes and iminodioxolanes are responsible for the configuration of products and the feasibility of the addition, respectively. A preliminary adduct, a spiro compound intermediate, is isolated, and its decomposition to oxazolidinone is demonstrated.
