Abstract
In the title compound, C34H32N2O7, the methyl group and methylene H atoms of the ethoxycarbonyl substituent are disordered over two positions with site occupancy factors for the major and minor conformers of 0.594 (8) and 0.406 (8), respectively. The unsubstituted ring of the pyrrolizine ring system exhibits a twist conformation, the other an envelope conformation. In the crystal structure, molecules are linked through C—H⋯O hydrogen bonds; intramolecular C—H⋯O interactions are also observed.
