Abstract
The cycloaddition reaction of benzonitriliop-nitrophenylmethanide to α, β-unsaturated epoxy ketones gives a mixture of stereoisomeric epoxycarbonyl pyrrolines. Only one of the isomers was isolated as pure compound. The structure, stereo- and regiochemistry of the isolated products was established by NMR and NOE measurements as well as by mass spectral data.
