Using CC1=C(C(=O)CS(=O)(=O)NC(C)C)[C@H](c2cccc([N+](=O)[O-])c2)C(C(=O)O[C@H](C)c2ccccc2)=C(C)N1 to produce CC1=C(/C=C/S(=O)(=O)NC(C)C)[C@H](c2cccc([N+](=O)[O-])c2)C(C(=O)O[C@H](C)c2ccccc2)=C(C)N1, please predict the agent for this reaction in SMILES notation in \boxed{$SMILES1, SMILES2, ...} format.
