Electrochemical　dearomative　spirocyclization　serves　as　a　green　and　sustainable　approach　to　convert　the　flat,　two-dimension　aromatic　feedstock　into　the　value-added　three-dimension　spirocyclic　architectures.　This　review　highlights　the　recent　advances,　emphasizes　mechanistic　discussions,　and　showcases　synthetic　applications　of　this　emerging　versatile　and　powerful　transformation.
