Abstract: The title compound, C₂₂H₂₀N₄O₂S, was synthesized by the intermolecular [3  +  2]-cycloaddition of azomethine ylide, derived from isatin and sarcosine by a decarboxylative route, and 2-benzylidene-5,6-dihydro-imidazo[2,1-b]thiazol-3-one. In the molecule, the two spiro junctions link a planar 2-oxoindoline ring, a pyrrolidine ring in an envelope conformation, and a 5,6-dihydroimidazo[2,1-b]thiazol-3(2H)-one ring. Two molecules are connected into a dimer by two N-HN hydrogen bonds.
