Task: Please generate a SMILES based on the text description.
Description: The molecule is a C4-dicarboxylate resuting from deprotonation of both carboxy groups of dihydroxyfumaric acid. It derives from a fumarate(2-). It is a conjugate base of a dihydroxyfumaric acid.
Result: O=C(O)/C([O-])=C(\[O-])C(=O)O
