Fully Atom-economic Access to Spiro-cyclic Skeletons through Photoredox-induced Hydrogen Transfer/Giese Addition/ Dearomative Cyclization/Protonation Cascade†

Herein, we have reported a fully atom- & highly step-economic cascade dearomatization with non-activated phenyl and other hetero-aryl rings for accesses to tethered-aniline spiro-lactam with broad substrate scopes. This protocol...
