Thermolysis of 3-(2-allyloxyphenyl)- or 3-(2-propargyloxyphenyl)-1-phthalimidoaziridine-2-carboxylic acid derivatives results in stereospecific intramolecularcycloaddition of intermediate N-phthalimidoazomethine ylides to double or triple carbon–carbon bonds. This leads to condensed N-phthalimidopyrrolidines, N-phthalimidopyrrolines, or products of their subsequent transformations. On the other hand
