[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is a 5-benzoyl-2,3-dihydro-1H-pyrrolizine-1-carboxylic acid that has R configuration. Unlike the S-enantiomer, it does not exhibit COX1 and COX2 inhibition, but does exhibit analgesic activity. Racemic ketorolac, known simply as ketorolac, is used (mainly as a tromethamine salt) as a potent analgesic for the short-term management of post-operative pain, and in eye drops to relieve the ocular itching associated with seasonal allergic conjunctivitis. It has a role as an analgesic. It is an enantiomer of a (S)-ketorolac."}, {"from": "gpt", "value": "[C][C][N][C][=Branch2][Ring1][C][=C][C][=C][Ring1][Branch1][C][=Branch1][C][=O][C][=C][C][=C][C][=C][Ring1][=Branch1][C@@H1][Ring1][S][C][=Branch1][C][=O][O]"}]
