Abstract

The title epoxide was obtained by spontaneous epoxidation of the corresponding unsaturated imide in air or by peracid oxidation. Unambiguous assignment of the 1H- and 13C-NMR spectra is achieved by comparison between analogous compounds and its X-ray structure confirms the exo,exo-configuration.
