User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a sesquiterpene lactone that is (3R,3a'R)-decahydrospiro[furan-3,2'-indene] carrying an oxo, methylene, acetoxy, [(2S)-2-methylbutanoyl]oxy, methyl and methyl groups at positions 2, 4, 3', 4', 7' and 7a', respectively. It has a role as a plant metabolite. It is a gamma-lactone, an acetate ester, a sesquiterpene lactone and an oxaspiro compound.
Assistant: This is a molecule that fits this description: C=C1COC(=O)[C@]12C[C@@]1(C)[C@H]([C@@H](OC(=O)[C@@H](C)CC)CC[C@@H]1C)[C@H]2OC(C)=O
