Abstract: In the title compound, C₂₀H₁₆N₂O₄, the oxetane and oxazoline rings are almost planar, while the heterocyclic ring of the indole moiety is distorted from planarity towards an envelope conformation. The phenyl ring is in a +sp conformation with respect to the indole moiety. The packing is stabilized by intermolecular C-HO and C-H interactions, as well as dipole-dipole and van der Waals interactions.
