User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an organic heterotetracyclic compound that is 2,3,10,12-tetrahydro-4H,11H-pyrano[2,3-a]xanthene-4,11-dione substituted by methyl groups at positions 6, 8, 10, and 10, and by hydroxy, isopropyl, methoxy, phenyl, and groups at positions 5, 12, 9, and 2, respectively (the S,R-enantiomer). It is isolated from the leaves of Baeckea frutescens and exhibits cytotoxicity against leukemia cells. It has a role as a metabolite and an antineoplastic agent. It is an ether, an extended flavonoid, an organic heterotetracyclic compound and a member of phenols.
Assistant: This is a molecule that fits this description: COC1=C(C)C2=C(C(=O)C1(C)C)[C@H](C(C)C)c1c(c(C)c(O)c3c1O[C@H](c1ccccc1)CC3=O)O2
