This work reports ad ual gold-catalyzed tetradehydro-Diels-Alderr eaction for the synthesis of nitrogencontaining aromatic heterocycles. Under the catalytic system (IPrAuNTf 2 /DIPEA), indolinesa nd carbazoles as well as other N-containinga romatic heterocyclesw ere prepared in high yields with good functional group tolerance. Unlike the traditional thermalt etradehydro-Diels-Alder reactions, diluted reaction concentration and radical prohibitors are not required for this protocol. Experimental data support am echanism involving gold vinylidene species, which undergoes a6 p electrocyclization, followed with 1,2-hydrogen shift.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
