The direct synthesis of sterically hindered aldehydes is highly challenging. Herein, we report a direct approach to generate such compounds via electroreductive cleavage of the C(sp3)–O bond of activated alcohols. Under the established reaction conditions, benzylic radical intermediates were efficiently generated. A subsequent radical–polar crossover generated carbanions that further reacted with N
