User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a monocarboxylic acid anion that is the conjugate base of pentalenolactone D, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of a pentalenolactone D.
Assistant: This is a molecule that fits your description: C[C@@H]1C(=O)OC[C@H]2C(C(=O)[O-])=C[C@@H]3CC(C)(C)C[C@]312
