9-{[4-(Dimethyl-amino)-benz-yl]amino}-5-(3,4,5-trimeth-oxy-phen-yl)-5,5a,8a,9-tetra-hydro-furo[3',4':6,7]naphtho-[2,3-d][1,3]dioxol-6(8H)-one

9-[(2-Meth-oxy-benz-yl)amino]-5-(3,4,5-trimeth-oxy-phen-yl)-5,5a,8a,9-tetra-hydro-furo[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.

In the title compound, C(30)H(32)N(2)O(7)·CH(4)O, the tetra-hydro-furan ring and the six-membered ring fused to it both display envelope conformations, with the ring C atom opposite the carbonyl group and the adjacent bridgehead C atom as the flaps, respectively. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link all moieties into ribbons along [010]. Weak inter-molecular C-H⋯O inter-actions consolidate the crystal packing further.
