[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is an azabicycloalkane that consists of ecgonine having phenylphosphonyl and alkyl groups attached to the hydroxy and carboxy groups respectively. Used as a transition state analogue of cocaine. It has a role as a hapten. It is an azabicycloalkane, a beta-alanine derivative and an organic phosphonate. It is functionally related to an ecgonine."}, {"from": "gpt", "value": "[C][N][C@H1][C][C][C@@H1][Ring1][Branch1][C@H1][Branch2][Ring1][#Branch1][C@H1][Branch1][Ring2][C][Ring1][#Branch1][O][P][=Branch1][C][=O][Branch1][=Branch2][C][=C][C][=C][C][=C][Ring1][=Branch1][O][C][=Branch1][C][=O][O][C][C][C][C][C][C][=Branch1][C][=O][N][C][C][C][=Branch1][C][=O][O]"}]
