[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is a synthetic phenylalanine derivative derived formally from the mycotoxin ochratoxin A by substitution at position 4 of the phenyl ring with a 5-carboxypentyl group. It has a role as a hapten. It is a N-acyl-L-phenylalanine, a member of isochromanes, a monocarboxylic acid amide, an organochlorine compound, a phenylalanine derivative and a diastereoisomeric mixture. It is functionally related to an ochratoxin A."}, {"from": "gpt", "value": "[C][C][C][C][=C][Branch2][Branch1][=Branch1][C][=C][Branch1][#C][C][=Branch1][O][=C][Ring1][=Branch1][C][=Branch1][C][=O][O][Ring1][O][O][C][=Branch1][C][=O][N][C@@H1][Branch2][Ring1][=Branch1][C][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][C][C][C][C][C][C][=Branch1][C][=O][O][C][=Branch1][C][=O][O][Cl]"}]
