User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is conjugate base of (R)-4-dehydropantoic acid; major species at pH 7.3. It is a hydroxy monocarboxylic acid anion and a 4-oxo monocarboxylic acid anion. It is a conjugate base of a (R)-4-dehydropantoic acid.
Assistant: This is a molecule that fits this description: CC(C)(C=O)[C@@H](O)C(=O)[O-]
