Alkynyl oxime ether underwent a gold-catalyzed domino reaction involving cyclization and subsequent Claisen-type rearrangement to afford trisubstituted isoxazoles in a direct, efficient, and regioselective manner. The products were successfully applied to the synthesis of unusual heterocycles as an illustration of the potential utility of the reaction.
