Using trimethylsulfonium, (3R,4aS,6aS,7aS,10aS,11aS,11bS)-3-hydroxy-7a-methylhexadecahydro-9H-cyclopenta[b]phenanthren-9-one to produce (3R,4aS,6aS,7aR,8R,10aR,11aS,11bS)-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"
    ]
}
