A facile synthesis and characterization of novel spiropyrrolidines is reported. Reaction of isatin and L-proline with semicarbazone gave the corresponding spiropyrrolidines. Intermolecular 1, 3-dipolarcycloaddition reaction of azomethine ylides, generated through decarboxylation route, with various semicarbazone as dipolarphiles has been investigated. A new class of functionalized spiroheterocycles with pyrrolidine moiety has been synthesized. The formation of spiro heterocycles was confirmedfatcat:qsgwfu4fgzhzvdu2ggiazkucle
