[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is an alkyl caffeate ester obtained by the formal condensation of trans-caffeic acid with nonan-2-ol. Isolated from the leaves of Piper sanguineispicum, it has been shown to exhibit antileishmanial activity. It has a role as an antileishmanial agent and a plant metabolite. It is functionally related to a 2-nonanol."}, {"from": "gpt", "value": "[C][C][C][C][C][C][C][C@H1][Branch1][C][C][O][C][=Branch1][C][=O][/C][=C][/C][=C][C][=Branch1][=Branch2][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][O]"}]
