ABSTRACT: In the title compound, C24H23N5O3, the oxindole ring system is nearly planar, with a dihedral angle between the two fused rings of 3.3?(1)°. In the fused pyrrolo-oxazole ring system, the oxazole and pyrrolidine rings adopt envelope conformations with the spiro C atom and one of the methyl-ene C atoms, respectively, as the flap atoms. In the crystal, mol-ecules are linked into a helical chain along the b axis via C-H?O inter-actions generating R 2 (1)(7) and R 2 (2)(8) ring motifs.
