On thermal treatment of the aziridines Sa-f intramolecular cycloaddition reactions of the intermedsteazomethine ylides 6 result in the formation of the metacyclophanes L-9. FoF 7a and 7b the conformational barriers are estimated to-be app';;;ximatzy 20 and 12 kcal/mol, respectively.

A stereoselective two step sequence for the construction of fused pyrrolidone ring systems has been developed which features the intramolecular [3+2] dipolar cycloaddition of unsaturated azomethine ylides. The ylides are produced upon reaction of aminomethylphosphonates with so-olefimic aldehydes, f
