実験手順

To a solution of racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(1-methylene-propyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (300 mg, 0.72 mmol) prepared in example 80b in methanol and dichloromethane (1:1, 50 mL) at −78° C. was passed a stream of ozone until the color of the solution turned blue. The reaction mixture was degassed with nitrogen, then methyl disulfide (5 mL) was added. The reaction was slowly warmed to room temperature and stirred overnight. The mixture was concentrated, and the residue was purified by chromatography (EtOAc:CH2Cl2=1:1) to give the racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-propionylspiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a white solid (Yield 160 mg, 50%)
