The reaction of cyclohexane furazan N-oxide with N-substituted maleimides involves successive 1,3-dipolar cycloadditions and gives substituted tetrahydroisoxazoloisoxazoles (isoxazolizidines) containing a pentanonitrile chain at the bridgehead.An x-ray crystal structure is reported for compound 9c, 2,3-endo-4,5-exo-3a-(4-cyanobutyl)-3,3a,4,5-tetrahydro-2H-isoxazoloisozazole-2,3:4,5-bis-.With 4,5-dimethyl- and -diphenyl-furazan N-oxides a similar reaction occurred with loss of a nitrile molecule.
