User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a D-5-monosubstituted hydantoin that is imidazolidine-2,4-dione in which the pro-R hydrogen at position 5 has been replaced by a phenyl group.
Assistant: This is a molecule that fits this description: O=C1NC(=O)[C@@H](c2ccccc2)N1
