[{"from": "human", "value": "Generate a molecule based on this description. The molecule is a malonate ester resulting from the formal condensation of the 6-hydroxy group of trans-rhaponticin with the carboxy group of malonic acid. It is a monosaccharide derivative, a malonate ester, a polyphenol, a stilbenoid, a monomethoxybenzene and an O-acyl carbohydrate. It is functionally related to a trans-rhaponticin. It is a conjugate acid of a 6-O-malonyl-trans-rhaponticin(1-)."}, {"from": "gpt", "value": "[C][O][C][=C][Branch2][Branch1][N][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][/C][=C][/C][=C][C][=Branch2][Ring2][O][=C][C][=Branch1][Ring2][=C][Ring1][=Branch1][O][C@H1][C@@H1][Branch2][Ring1][=N][C@H1][Branch2][Ring1][Branch2][C@@H1][Branch2][Ring1][Ring1][C@H1][Branch1][Ring2][O][Ring1][=Branch1][C][O][C][=Branch1][C][=O][C][C][=Branch1][C][=O][O][O][O][O][O][O]"}]
