1 '-Benzyl-1-(2,4-dimethoxyphenyl)-3-phenoxyspiro[azetidine-2,3 '(3H)-indole]-2 ',4(1H)-dione

Abstract

The title compound, C31H26N2O5, is a compound with a spiro junction between beta-lactam and isatin ring systems. Its four-and five-membered rings are nearly planar, with maximum deviations of -0.020 (1) and 0.050 (1) angstrom for their carbonyl C atoms, respectively. The dihedral angle between these two rings is 86.44 (5)degrees. The crystal structure is stabilized by intramolecular C-H center dot center dot center dot O hydrogen-bonding and van der Waals interactions.
