A novel and efficient TEMPO-catalyzed synthesis of 5-substituted isoxazoles from propargylic ketones and TMSN3 via a radical mechanism process is described. This methodology provides an easy access to a variety of useful 5-substituted isoxazoles from simple and readily available propargylic ketones and TMSN3 in good to excellent yields. A plausible reaction mechanism for this process is proposed.
