Thermolysis of dimethyl esters of stereoisomeric phthalimidoaziridine-2,3-dicarboxylic acids in the presence of dimethyl fumarate, dimethyl maleate, and N-phenylmaleimide occurred stereo-specifically and stereoselectively led to the formation of derivatives of 1-phthalimidopyrrolidine, products of 1,3-dipolar additrion of intermediately arising azomethine ylides. In keeping with the rules of the conservation of orbital symmetry the thermal opening of the 2,3-disubstituted 1-phthalimidoaziridines into azomethine ylides occurred conrotatory. The relative positions of the substituents in the dipolarophiles is retained in the reaction products indicating the concerted addition mechanism.
