  • 1'-(2-(4-chlorophenyl)quinoline-4-carbonyl)spiro[chroman-2,4'-piperidin]-4-one [ No CAS ]
YieldReaction ConditionsOperation in experiment
General procedure: To a solution of tert-butyl 4-oxospiro[chroman-2,4′-piperidine]-1′-carboxylate (1.6 g, 5 mmol) in dichloromethane (20 mL) was added trifluoroacetic acid (2.5 mL). The reaction mixture was stirred at room temperature for 2 h and the solvent was removed under reduced pressure to give crude spiro[chroman-2,4′-piperidin]-4-one 11. The resulting solid was used directly for the next step reaction without further purification. A mixture of substituted quinoline-4-carboxylic acid (1, 5 mmol), NEt3 (0.61 g, 6 mmol) and HATU (1.9 g, 5 mmol) in DMF (10 mL) was stirred at room temperature for 0.5 h, followed by the abovementioned spiro[chroman-2,4′-piperidin]-4-one 11. The reaction mixture was stirred overnight at room temperature after which time it was diluted with EtOAc (100 mL) and washed with water (60 mL × 2). The organic extract was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude material was purified by chromatography to afford substituted 1′-(quinoline-4-carbonyl)spiro[chroman-2,4′-piperidin]-4-ones 12.

YieldReaction ConditionsOperation in experiment
General procedure: To a solution of tert-butyl 4-oxospiro[chroman-2,4?-piperidine]-1?-carboxylate (1.6 g, 5 mmol) in dichloromethane (20 mL) was added trifluoroacetic acid (2.5 mL). The reaction mixture was stirred at room temperature for 2 h and the solvent was removed under reduced pressure to give crude spiro[chroman-2,4?-piperidin]-4-one 11. The resulting solid was used directly for the next step reaction without further purification. A mixture of substituted quinoline-4-carboxylic acid (1, 5 mmol), NEt3 (0.61 g, 6 mmol) and HATU (1.9 g, 5 mmol) in DMF (10 mL) was stirred at room temperature for 0.5 h, followed by the abovementioned spiro[chroman-2,4?-piperidin]-4-one 11. The reaction mixture was stirred overnight at room temperature after which time it was diluted with EtOAc (100 mL) and washed with water (60 mL × 2). The organic extract was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude material was purified by chromatography to afford substituted 1?-(quinoline-4-carbonyl)spiro[chroman-2,4?-piperidin]-4-ones 12.
