Hydride hijacked by “hydrogen”! N‐Alkylindoles and N‐alkylindolines were obtained in the redox amination of indoline with aldehyde, which was tuned by a hydrogen‐bond effect. Salicylaldehyde gave the indoline‐type product via intermolecular hydride transfer, while other aromatic aldehydes gave the indole‐type product via intramolecular hydride transfer.
