چکیده
The title compound, C(16)H(14)O(5), was prepared from the reaction of 3-carbethoxy-coumarin with furan in the presence of AlCl(3) as catalyst. In the crystal, inter-molecular C-H⋯O hydrogen-bonding inter-actions between four mol-ecules lead to a tetra-mer in the unit cell. The furan ring is anti-periplanar [C-C-C-O = 167.9 (13)°] and the ethoxy-carbonyl group is (-)anti-clinal [C-C-C-O = -128.6 (14)°] to the lactone ring.
