Electro-catalyzed, solvent-controlled divergent decarboxylative annulation and hydroaminomethylation of cyclic aldimines with <i>N</i>-arylglycines

Herein, we reported a sustainable and simple method involving electrochemical-catalyzed decarboxylative annulation and hydroaminomethylation of cyclic aldimines with <i>N</i>-arylglycines by switching the reaction solvents. When the reaction was carried out in MeCN/H₂O or H₂O, the resulting products included imidazolidine-fused sulfamidates and C4-aminomethylated cyclic aldimines, obtained in moderate to good yields, respectively. Mechanistically, a radical pathway was proposed to be involved in this approach.
