Abstract
In the title compound, C(31)H(29)NO(5), the methyl carboxyl-ate and dimethyl-amino groups on the naphtho-pyran group are almost coplanar with the naphtho-pyran ring system [r.m.s. deviations = 0.08 (2) and 0.161 (2) Å, respectively]. The dihedral angle between the methyl carboxyl-ate and dimethyl-amino groups is 4.9 (1)°. The pyran ring has an envelope conformation with the quaternary C atom out of plane by 0.4739 (13) Å. The meth-oxy-phenyl substituent forms a dihedral angle of 16.6 (1)° with the plane of the benzene ring, while the other meth-oxy-phenyl group is almost coplanar, making a dihedral angle of 1.4 (1)°.
