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
Abstract
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.
