A novel and efficient electrochemical method for electroselective and controlled cross-coupling of isoindolinones with equivalent alcohols has been developed without the need for metal catalysts and strong bases under mild conditions. The reaction provides a novel strategy for the controllable and effective synthesis of 3-alkoxyl and -hydroxymethyl-substituted isoindolinones, which is adjusted by 4-OH-TEMPO and tolerates various substrates. This protocol is an efficient tool for the construction of C-O and C-N bonds with high chemoselectivity.

An efficient and practical electrochemical method for selective reduction of cyclic imides has been developed using a simple undivided cell with carbon electrodes at room temperature. The reaction provides a useful strategy for the rapid synthesis of hydroxylactams and lactams in a controllable manner, which is tuned by electric current and reaction time, and exhibits broad substrate scope and high functional group tolerance even to reduction-sensitive moieties. Initial mechanistic studies suggest that the approach heavily relies on the utilization of amines (e.
