A straightforward strategy for an intramolecular transfer oxygenation of alkynes and cycloisomerization of 2‐nitroalkynes to synthesize a wide range of C2‐quaternary indolin‐3‐ones using a copper/diboron system was developed. The desired allylation, benzylation, and propargylation products were obtained in moderate to excellent yields with good functional group tolerance.
