Dioxopyrrolines. XLI. X-Ray Crystallographic Determination of the Stereochemistry of an Azatritricyclo2.6>decane Derivative Obtained by Photocycloaddition of Cyclopentadiene to 4-Ethoxycarbonyl-5-phenyl-1H-pyrrole-2,3-dione

The stereochemistry of one of the photoadduct of cyclopentadiene to 4-ethoxy-5-phenyl-1H-pyrrole-2,3-dione, 6-ethoxycarbonyl-2-phenyl-3-azatricyclo2,6>decan-9-ene-4,5-dione, was established as cis-syn-cis by an X-ray crystalographic analysis.
