چکیده
The title compound, C17H18O5, was synthesized by a base-free catalytic Wittig reaction. The mol-ecule consists of a diethyl itaconate unit, which is connected via the C=C double bond to a benzo-furan moiety. The benzo-furan ring system (r.m.s. deviation = 0.007 Å) forms dihedral angles of 79.58 (4) and 12.12 (10)° with the mean planes through the cis and trans eth-oxy-carbonyl groups, respectively. An intra-molecular C-H⋯O hydrogen bond involving the O atom of the benzo-furan moiety is observed. In the crystal, mol-ecules are linked into ribbons running parallel to the b axis by C-H⋯O hydrogen bonds.

In the title compound, C(15)H(14)O(2)S, the three fused rings are roughly coplanar, the largest deviation from the mean plane being 0.1285 (13) Å for the S atom. An intra-molecular N-H⋯O hydrogen bond generates an S6 ring. In the crystal, inter-molecular C-H⋯O hydrogen bonds form R(2) (2)(14), R(2) (2)(13) and R(3) (2)(17) ring motifs, building a layer parallel to (100).
