Abstract
In the title compound, C27H28N2O3, each of the pyrrolidine rings adopts a twisted conformation, as does the cyclopentane ring. The indane ring has an r.m.s deviation of 0.0693 Å. The dihedral angle between the mean plane of the pyrrolizine ring and indane system is 82.58 (1)°. The piperidine ring has the methyl substituent in an equatorial position and adopts a twisted chair conformation. The molecular structure is stabilized by a weak intramolecular O—H⋯N interaction.
