of iminyl radical‐triggered 1,5‐hydrogen atom transfer and (5+2) or (5+1) annulation processes, a series of structurally novel and interesting azepine and spiro‐tetrahydropyridine derivatives have been successfully prepared in moderate to good yields. This method utilizes FeCl2 as the catalyst and readily available oximes as five‐atom units, while showcasing broad substrate scope and good functional

A phase‐transfer catalytic 1,3‐dipolar [3+2] cycloaddition grants rapid generation of various trifluoromethyl spiro‐fused[succinimide‐pyrrolidine‐oxindole]s that might be of great utility for drug discovery. The gram‐scale reaction in conjunction with the derivatizations of the product demonstrate the synthetic potential of this methodology. The reaction mechanism is also discussed.
