A novel heteroannulation reaction between α‐amino imides and in situ generated arynes has been developed for the synthesis of 2,2‐disubstituted indolin‐3‐ones. An enantioselective total synthesis of the marine alkaloid (+)‐hinckdentine A was subsequently accomplished using this reaction as a key step.
