چکیده
In the title compound, C(13)H(15)NO(3)S, the sole classical hydrogen-bond donor is involved in an intra-molecular O-H⋯N hydrogen bond. In the crystal structure, pairs of mol-ecules related by inversion centres are linked by pairs of weak inter-molecular C-H⋯O inter-actions; these centrosymmetric pairs are, in turn, linked further by weak inter-molecular C-H⋯O inter-actions, forming two-dimensional sheets oriented parallel to (101).

In the title compound, C(24)H(21)ClN(4)O(2)S, the two adjacent spiro junctions link an almost planar (r.m.s. deviation = 0.017 Å) 2-oxindole ring, a hexa-hydro-1H-pyrrolizine ring and a tetra-hydro-imidazo[2,1-b]thia-zole ring. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, generating an R(2) (2)(16) loop.
