4'-(4-Chlorophenyl)-1'-methyl-4'',5'',6'',7''-tetrahydro-1H-indole-3-spiro-2'-pyrrolidine-3'-spiro-2''-(thiazolo[3,2-a]pyrimidine)-2(3H),3''(2''H)-dione

Abstract: The title compound, C₂₃H₂₁ClN₄O₂S, was synthesized by the intermolecular [3  +  2]-cycloaddition of azomethine ylide, derived from isatin and sarcosine by a decarboxylative route, and 2-(4-chlorobenzylidene)-6,7-dihydro-5H-thiazolo[3,2-a]pyrimidin-3-one. In the molecule, the two spiro junctions link a planar 2-oxindole ring, a pyrrolidine ring in an envelope conformation and a 6,7-dihydro-5H-thiazolo[3,2-a]pyrimidin-3-one ring. Two molecules are connected into a dimer by two N-HN hydrogen bonds
