Task: Please create a SMILES based on the text description below.
Description: 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.
Result: O=C1C=C/C(=C/C(=O)C(=O)O)O1
