Task: Please give me a molecule SMILES based on the text description below.
Description: The molecule is a tetracyclic sesquiterpene lactone obtained by formal epoxidation of the 4-methylene group of pentalenolactone E. It has a role as a bacterial metabolite. It is a sesquiterpene lactone, an organic heterotricyclic compound, a spiro-epoxide and an alpha,beta-unsaturated monocarboxylic acid. It is a conjugate acid of a pentalenolactone F(1-).
Result: CC1(C)C[C@H]2C=C(C(=O)O)[C@@H]3COC(=O)[C@]4(CO4)[C@]23C1
