Abstract

7-(Ethoxymethyl)-4′,4′-dimethyl-2-(3-nitrophenyl)-2′,6′,8-trioxo-5,7-diazaspiro[bicyclo[3.3.1]nonane-3,1′-cyclohexane]-1-carbonitrile has been synthesized by the reaction of 2-amino-7,7-dimethyl-4-(3-nitrophenyl)-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile with aqueous formaldehyde in ethanol under reflux, and its molecular and crystal structures have been determined by spectral methods and X-ray analysis.
