Using trimethylsulfonium, (3S,4aS,6aR,7aS,10aS,11aR,11bR)-3-hydroxy-7a-methylhexadecahydro-8H-cyclopenta[b]phenanthren-8-one to produce (3S,4aS,6aR,7aS,8S,10aS,11aR,11bR)-7a-methylhexadecahydrospiro[cyclopenta[b]phenanthrene-8,2'-oxiran]-3-ol, please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [
        "On1nnc2ccccc21",
        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
