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
