[{"from": "human", "value": "Use the given information to create a molecule that fulfills the desired purpose. The molecule is a ring assembly that consists of robinetinidol attached to a (+)-catechin unit resulting in a bond between C-4 of the pyran ring and C-8 of the benzopyran ring. It is isolated from Acacia mearnsii. It has a role as a metabolite. It is a catechin and a ring assembly. It is functionally related to a robinetinidol and a (+)-catechin."}, {"from": "gpt", "value": "[C][C@@H1][Branch2][=Branch1][=C][C@H1][Branch2][Branch1][N][O][C][=C][Ring1][=Branch1][C][=Branch2][Branch1][C][=C][C][=Branch2][Ring2][N][=C][Ring1][=Branch1][C@H1][C@@H1][Branch2][Ring2][Ring1][C@H1][Branch1][#C][O][C][=C][Ring1][=Branch1][C][=C][C][=Branch1][Ring2][=C][Ring1][=Branch1][O][C][=C][C][=Branch1][N][=C][Branch1][Branch2][C][=Branch1][Ring2][=C][Ring1][=Branch1][O][O][O][O][O][O][C][=C][C][=Branch1][=Branch2][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][O][O]"}]
