A new iodine-promoted domino reaction of 2-aminochromene-3-carbonitriles with various isocyanates was described, and a set of polyfunctionalized N-substituted 2-aminoquinoline-3-carbonitriles with high regioselectivity were successfully synthesized under microwave heating. In this reaction, the ring-opening/recyclization process occurs unexpectedly at the ring of 4H-pyran with different isocyanates.
