The development of tandem radical Csp3-H functionalization/ cycloaddition of methylketone, tert-butyl nitrite, and maleimide has been reported herein. A variety of pyrrolo[3,4-d]isoxazolines have been successfully synthesized under metal-free conditions with excellent functional group compatibility. X-ray crystallography of the pyrrolo[3,4-d]isoxazoline was obtained and the reaction mechanism was
