A methodology of FeBr3-catalyzed tandem reaction of N-propargylamides with disulfides or diselenides for the formation of oxazole derivatives has been developed. The strategy includes several steps in one pot. Series of N-propargylamides and disulfides were suitable as substrates in this transformation for synthesizing the corresponding oxazole derivatives in moderate to good yields.
