Benzo[d]isoxazoles are found to act as novel nucleophiles to undergo gold-catalyzed [5 + 1] or [5 + 2] cycloaddition reactions with ynamides. The reaction provides a concise and chemoselective access to polysubstituted 2H-benzo[e][1,3]oxazines or benzo[f][1,4]oxazepines. In addition, benzo[d]isoxazoles can also react with gold-carbene intermediates derived from propargyl esters to afford [5 + 1] annulation products.
