User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a 2-oxo monocarboxylic acid anion that is the conjugate base of 2-oxo-3-(5-oxofuran-2-ylidene)propanoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of a 2-oxo-3-(5-oxofuran-2-ylidene)propanoic acid.
Assistant: This is a molecule that fits this description: O=C1C=C/C(=C/C(=O)C(=O)[O-])O1
