An environmentally benign and proficient electro‐oxidative tandem azidation‐radical cyclization strategy is reported. Manganese‐catalyzed electrochemical reaction in an undivided cell at room temperature and the use of NaN3 as the cheapest azide source are the key features of this protocol. Using this approach, a series of oxindole and quinolinone derivatives are synthesized in high yields. The synthesized
