Ethyl 4′-ethenyl-2′-oxo-4-phenyl-2-(3,4,5-trimethoxyphenyl)spiro[pyrrolidine-3,3′-indoline]-5-carboxylate monohydrate

Abstract

In the title compound, C31H32N2O6·H2O, the pyrrolidine ring adopts an envelope conformation. The ethyl C atoms of the ethoxycabonyl group are disordered over two positions with occupancies of ca 0.80 and 0.20. Intramolecular N—H...O hydrogen bonds form S(5) and S(6) ring motifs. Molecules are linked into a three-dimensional framework by O—H...O, N—H...O and C—H...O hydrogen bonds, and by C—H...π interactions.
