Abstract
On heating of the 2-amino-5-nitrobenzonitrile 1 with cyclohexanone 2a in the presence of catalyst, the novel compound 6-nitrospiro[3,1-benzoxazine-2,1′-cyclohexan]-4(1H)-imine 5a was formed. Also, reaction of 1 with cyclopentanone 2b or cycloheptanone 2c afforded 5b or 5c respectively. All new compounds were identified by 1H NMR, 13C NMR, IR, MS spectra and elemental analysis. The crystal structure of product 5a was determined by crystal X-ray diffraction. And the mechanism for these reactions is proposed.
