The isoxazolo[2, 3‐ a ]quinoxalines 11a, b and pyrrolo[1, 2‐ a ]quinoxalines 12a, b were selectively synthesized from the 2‐substituted 6‐chloroquinoxaline 4‐oxides 10a, b . The pyrrolo[1, 2‐ a ]quinoxalines 12a, b were clarified to be produced by the ring transformation of the isoxazolo[2, 3‐ a ]quinoxalines 11a, b .
