9-[(2-Meth­oxy­benz­yl)amino]-5-(3,4,5-trimeth­oxy­phen­yl)-5,5a,8a,9-tetra­hydro­furo[3′,4′:6,7]naphtho­[2,3-d][1,3]dioxol-6(8H)-one

In the title compound, C₃₀H₃₁NO₈, the tetra­hydro­furan 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 intra­molecular N—H...O hydrogen bond is present. In the crystal, weak inter­molecular C—H...O hydrogen bonds link the mol­ecules into chains parallel to the c axis.
