摘要
The title compound, C26H19ClN4O2S.0.5C(4)H(8)O(2), was synthesized by the intermolecular [3+2]-cycloaddition of azomethine ylide, derived from isatin and sarcosine by a decarboxylative route, and 2-(2-chlorobenzylidene) benzo[ 4,5] 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 planar benzo[ 4,5]imidazo[ 2,1-b] thiazol-3(2H)-one ring. Two molecules are connected by N-H...O hydrogen bonds to a molecule of dioxane on an inversion center, with an N...O distance of 2.823 (2) Angstrom.
