9-[(Furan-2-ylmeth-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.

ABSTRACT: In title compound, C(27)H(27)NO(8), the dihydrofuran-2(3H)-one ring and the six-membered ring fused to it both display envelope conformations. The dihedral angle between the benzene ring of the benzo[d][1,3]dioxole group and the other benzene ring is 60.59?(2)°. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. The furan ring is disordered over two sets of sites with occupancies of 0.722?(7) and 0.278?(7).
