User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a 2-oxo monocarboxylic acid that is pyruvic acid substituted at position 3 by a 5-oxofuran-2-ylidene group. It is a 2-oxo monocarboxylic acid and a butenolide. It derives from a pyruvic acid. It is a conjugate acid of a 2-oxo-3-(5-oxofuran-2-ylidene)propanoate.
Assistant: This is a molecule that fits this description: O=C1C=C/C(=C/C(=O)C(=O)O)O1
