The annulation of propargyl amines with electron-deficient alkynes in the presence of silver salts affording pyridines and pyrroles has been developed. The chemoselective [4+2] or [3+2] annulation approach to pyridines or pyrroles depends on the structures of propargyl amines and the different reaction conditions.
