A series of N-allenyl amides was prepared conveniently from N-propargyl amides in good to excellent yields via a modified procedure developed in this group. The palladium-catalyzed coupling–cyclization of these prepared N-allenyl amides in the presence of organic iodides has been developed affording the oxazoline derivatives efficiently.
