User: Can you generate the SMILES of a molecule based in this description:
The molecule is an organic heterotetracyclic compound and 19-membered macrocyclic lactam that is maytansine in which one of the hydrogens of the terminal N-acetyl group is replaced by a sulfanylmethyl group. It has a role as an antineoplastic agent and a tubulin modulator. It is an alpha-amino acid ester, a carbamate ester, an epoxide, an organic heterotetracyclic compound, an organochlorine compound, a thiol and a maytansinoid. It derives from a maytansine.
Assistant: Sure, here you go: COc1cc2cc(c1Cl)N(C)C(=O)C[C@H](OC(=O)[C@H](C)N(C)C(=O)CCS)[C@]1(C)O[C@H]1[C@H](C)[C@@H]1C[C@@](O)(NC(=O)O1)[C@H](OC)/C=C/C=C(\C)C2
