[{"from": "human", "value": "Generate a molecule based on this description. The molecule is a member of the class of rotenones that is 13,13a-dihydro-3H-chromeno[3,4-b]pyrano[2,3-h]chromen-7(7aH)-one substituted with geminal methyl groups at position 3, hydroxy group at position 7a and methoxy groups at positions 9 and 10 (the 7aR,13aR stereoisomer). It is isolated from the leaves and twigs of Antheroporum pierrei and exhibits antineoplastic and pesticidal activities. It has a role as a pesticide, an antineoplastic agent and a metabolite. It is an organic heteropentacyclic compound, an aromatic ether, a cyclic ketone and a member of rotenones."}, {"from": "gpt", "value": "[C][C][Branch2][Ring2][#C][C][=C][C][=C][Branch1][Ring2][O][Ring1][=Branch1][C][=C][C][=C][Ring1][#Branch1][O][C@@H1][C][O][C][=C][C][=Branch2][Ring1][Ring2][=C][Branch1][#C][C][=C][Ring1][=Branch1][C@@][Ring1][#Branch2][Branch1][Branch1][C][Ring1][=C][=O][O][O][C][O][C][C]"}]
