[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an organic heteropentacyclic compound that is (5R)-8-[(6,7-difluoroquinolin-3-yl)methyl]-5-ethyl-5-hydroxy-1,4,5,8-tetrahydrooxepino[3,4-c]pyridine-3,9-dione in which position 7 of the oxepinopyridine moiety is joined to position 3 of the difluoroquinoine ring by a single bond. An E-ring modified camptothecin analogue that has greater lactone stability in plasma compared with other topoisomerase I inhibitors. It has a role as an EC 5.99.1.2 (DNA topoisomerase) inhibitor and an antineoplastic agent. It is an organic heteropentacyclic compound, an organofluorine compound, a tertiary alcohol, an epsilon-lactone and an organonitrogen heterocyclic compound. It is functionally related to a (R)-homocamptothecin."}, {"from": "gpt", "value": "[C][C][C@][Branch2][Ring2][N][C][C][=Branch1][C][=O][O][C][C][=C][Ring1][Branch2][C][=C][C][=C][Branch1][=Branch2][C][N][Ring1][Branch1][C][Ring1][=Branch2][=O][C][=C][C][=C][Branch1][N][C][=Branch1][Branch2][=C][C][Ring1][=Branch1][=N][Ring1][=C][F][F][O]"}]
