An unprecedented gold-catalyzed procedure for the synthesis of polysubstituted 4-quinolones from 1-(2′-Azidoaryl) propynols is described. The reaction undergoes an intramolecular nucleophilic attack of the azide group to the Au-Activated triple bonds in a 6-endo-dig manner and subsequent gold-Assisted expulsion of N2 to furnish an α-imino gold carbene intermediate, which triggers a 1,2-carbon migration and finally is converted to 2,3-disubstituted 4-quinolone.
