An efficient multicomponent dipolar cycloaddition for the synthesis of polycyclic fused pyrrolizidines was developed using N-aromatic zwitterions, aldehydes, and amino acids. The developed reactions proceed through azomethine ylides generated in situ from the decarboxylated reactions of aldehydes and amino acids followed by the [3 + 2] cycloaddition of N-aromatic zwitterions under mild reaction conditions.
