A metal‐free and oxidant‐free method for the one‐pot preparation of quinazolin‐4(3H)‐ones enabled by electrochemical oxidation is described. Together with 2‐aminobenzamides, a variety of aldehydes were successfully applied to an acid‐catalyzed annulation and direct anodic oxidation cascade, affording structurally diverse quinazoline‐4(3H)‐ones in good to excellent yields. Additionally, certain alcohols
