5'-Chlorospiro[1,3-dioxolane-2,3'-indolin]-2'-one: a potential anticonvulsant

A. De

Abstract: The title compound, C₁₀H₈ClNO₃, is a significant anticonvulsant agent. The indolinone system is essentially planar, the dihedral angle between the rings being 2.24 (8)°. The dioxolane ring adopts an envelope conformation; the dihedral angle between the plane through its four coplanar atoms and the indolinone system is 89.8 (1)°. The crystal structure is stabilized by a three-dimensional network of intermolecular N-HO hydrogen bonds.
