Ethyl (2E)-2-(2H-1,3-benzodioxol-5-yl­methyl­idene)-4-chloro-3-oxobutano­ate

In the title compound, C(14)H(13)ClO(5), the five-membered ring is in an envelope conformation with the methyl­ene C-atom being the flap. The conformation about the C=C double bond [1.341 (2) Å] is E. The chloro­propan-2-one residue is approximately orthogonal to the remaining mol­ecule [dihedral an...

Descripción
Sumario:In the title compound, C(14)H(13)ClO(5), the five-membered ring is in an envelope conformation with the methyl­ene C-atom being the flap. The conformation about the C=C double bond [1.341 (2) Å] is E. The chloro­propan-2-one residue is approximately orthogonal to the remaining mol­ecule [dihedral angle = 88.03 (6)°]. In the crystal, the mol­ecules associate via C—H⋯O inter­actions, involving both carbonyl-O atoms, giving rise to an undulating two-dimensional array in the ac plane.
