dual gold‐catalyzed tetradehydro‐Diels–Alderreaction for the synthesis of nitrogen‐containing aromatic heterocycles. Under the catalytic system (IPrAuNTf2/DIPEA), indolines and carbazoles as well as other N‐containing aromatic heterocycles were prepared in high yields with good functional group tolerance. Unlike the traditional thermal tetradehydro‐Diels–Alderreactions, diluted reaction concentration
