(3R*)-Methyl 3-[(2S*)-4,6-dimethoxy-2-(4-methoxyphenyl)-3-oxo-2,3-dihydro-1-benzofuran-2-yl]-2-methoxycarbonyl-3-phenylpropionate.

The title compound, C(29)H(28)O(9), was isolated from the reaction of 4,6-dimeth-oxy-2-(4-methoxy-phen-yl)-3-benzofuran and α-methoxy-carbonyl-cinnaminate. The two aromatic rings form a dihedral angle of 22.7 (1)°. One methoxy-carbonyl group is disordered between two orientations in a 0.612 (4):0.388 (4) ratio. The crystal structure exhibits no significantly short inter-molecular contacts.
