Methyl (2E)-2-[(2,4-dioxo-1,3-thia-zolidin-3-yl)meth-yl]-3-phenyl-prop-2-enoate.

In the title compound, C(14)H(13)NO(4)S, the thia-zolidine ring is essentially planar [maximum deviation = 0.010 (2) Å for the carbonyl C atom between the N and S atoms] and is oriented at a dihedral angle of 60.1 (1)° with respect to the benzene ring. In the crystal, mol-ecules are linked into zigzag chains running along the c axis by C-H⋯O hydrogen bonds. The crystal packing is further stabilized by C-H⋯π inter-actions involving the benzene ring.
