User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a monocarboxylic acid anion that is the conjugate base of pentalenolactone F, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of a pentalenolactone F.
Assistant: This is a molecule that fits your description: CC1(C)C[C@H]2C=C(C(=O)[O-])[C@@H]3COC(=O)[C@]4(CO4)[C@]23C1
