User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is the alpha,beta-unsaturated monocarboxylic acid that is the active nucleus for the synthesis of cephalosporins and intermediates. It derives from a cephalosporanic acid. It is a tautomer of a 7beta-aminocephalosporanic acid zwitterion.
Assistant: This is a molecule that fits your description: CC(=O)OCC1=C(C(=O)O)N2C(=O)[C@@H](N)[C@H]2SC1
