Abstract [3+2]-Cycloaddition of 2-methoxycarbonylmethylene-5-phenyl-2,3-dihydro-3-furanone to acetone azine has been studied. This results in a monospirocycloadduct,viz., 9,9-dimethyl-6-methoxycarbonyl-2-phenyl-1-oxa-7,8-diazaspiro[4.4]nona-2,6-dien-4-one. Its structure has been confirmed by X-ray diffraction analysis.
