Synthesis reveals new compound structure in a chemical reaction, suggesting potential applications in materials science.
Based on 2-amino-7,7-dimethyl-4-(3-nitrophenyl)-5-oxo-5,6,7,8-tetrahydro-4-chromene-3-carbonitrile and formalin when heated in ethanol was obtained 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, the structure of which has been studied using spectral methods and X-ray diffraction analysis.
