1′-(2-Chlorophenyl)-5,6,5′,6′,7′,7a′-hexahydro-1′H,1′′H-dispiro[imidazo[2,1-b][1,3]thiazole-2,2′-pyrrolizine-3′(2′H),3′′-indole]-2′′,3(2H,3′′H)-dione

Abstract

In the title compound, C24H21ClN4O2S, the two adjacent spiro junctions link an almost planar (r.m.s. deviation = 0.017 Å) 2-oxindole ring, a hexa­hydro-1H-pyrrolizine ring and a tetra­hydro­imidazo[2,1-b]thia­zole ring. In the crystal, inversion dimers linked by pairs of N—H⋯N hydrogen bonds occur, generating an R 2 2(16) loop.
