Abstract

In the title compound, C(30)H(31)NO(8), the tetra-hydro-furan ring and the six-membered ring fused to it both display envelope conformations, both having the same C atom as the flap. The dihedral angles between the benzene ring of the benzo[d][1,3]dioxole ring system and the other two benzene rings are 53.73 (3) and 83.30 (2)°. An intra-molecular N-H⋯O hydrogen bond is present. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the c axis.
